Abstract

We report a search for the charmless hadronic decay B0 -> \eta \pi^0 with a data sample corresponding to an integrated luminosity of 694 fb^{-1} containing 753\times 10^6 B\bar{B} pairs. The data were collected by the Belle experiment running on the \Upsilon(4S) resonance at the KEKB e^+e^- collider. We measure a branching fraction \mathcal{B}(B^0\to\eta\pi^0)=(4.1^{+1.7+0.5}_{-1.5-0.7})\times 10^{-7}, where the first uncertainty is statistical and the second is systematic. Our measurement gives an upper limit of \mathcal{B}(B^0\to\eta\pi^0)

Abstract

We present a search for the rare leptonic decays B+?e+?e and B+??+??, using the full (4S) data sample of 772�106 BB� pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. One of the B mesons from the (4S)?BB� decay is fully reconstructed in a hadronic mode, while the recoiling side is analyzed for the signal decay. We find no evidence of a signal in any of the decay modes. Upper limits of the corresponding branching fractions are determined as B(B+?e+?e)

Abstract

Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere is important to better understand the global carbon cycle, support the development of climate policies, and project future climate change. Here we describe data sets and a methodology to quantify all major components of the global carbon budget, including their uncertainties, based on the combination of a range of data, algorithms, statistics and model estimates and their interpretation by a broad scientific community. We discuss changes compared to previous estimates, consistency within and among components, alongside methodology and data limitations. CO2 emissions from fossil-fuel combustion and cement production (EFF) are based on energy statistics, while emissions from land-use change (ELUC), mainly deforestation, are based on combined evidence from land-cover change data, fire activity associated with deforestation, and models. The global atmospheric CO2 concentration is measured directly and its rate of growth (G ATM) is computed from the annual changes in concentration. The mean ocean CO2 sink (SOCEAN) is based on observations from the 1990s, while the annual anomalies and trends are estimated with ocean models. The variability in SOCEAN is evaluated for the first time in this budget with data products based on surveys of ocean CO2 measurements. The global residual terrestrial CO2 sink (SLAND) is estimated by the difference of the other terms of the global carbon budget and compared to results of independent dynamic global vegetation models forced by observed climate, CO2 and land cover change (some including nitrogen-carbon interactions). All uncertainties are reported as ±1σ , reflecting the current capacity to characterise the annual estimates of each component of the global carbon budget. For the last decade available (2003-2012), EFF was 8.6±0.4 GtC yr-1, ELUC 0.9±0.5 GtC yr-1, GATM 4.3±0.1 GtC yr-1, SOCEAN 2.5±0.5 GtC yr -1, and SLAND 2.8±0.8 GtC yr-1. For year 2012 alone, EFF grew to 9.7±0.5 GtC yr-1, 2.2% above 2011, reflecting a continued growing trend in these emissions, G ATM was 5.1±0.2 GtC yr-1, SOCEAN was 2.9±0.5 GtC yr-1, and assuming an ELUC of 1.0±0.5 GtC yr-1 (based on the 2001-2010 average), S LAND was 2.7±0.9 GtC yr-1. GATM was high in 2012 compared to the 2003-2012 average, almost entirely reflecting the high EFF. The global atmospheric CO2 concentration reached 392.52±0.10 ppm averaged over 2012. We estimate that EFF will increase by 2.1% (1.1- 3.1 %) to 9.9±0.5 GtC in 2013, 61% above emissions in 1990, based on projections of world gross domestic product and recent changes in the carbon intensity of the economy.With this projection, cumulative emissions ofCO2 will reach about 535±55 GtC for 1870-2013, about 70% from EFF (390±20 GtC) and 30% from ELUC (145±50 GtC). This paper also documents any changes in the methods and data sets used in this new carbon budget from previous budgets (Le Quéré et al., 2013). All observations presented here can be downloaded from the Carbon Dioxide Information Analysis Center (doi:10.3334/CDIAC/GCP-2013-V2.3).

Abstract

The cross sections of the processes $e^+ e^- \to K^+ K^- J/\psi$ and $K_S^0K_S^0J/\psi$ are measured via initial state radiation at center-of-mass energies between the threshold and 6.0~GeV using a data sample of 980~fb$^{-1}$ collected with the Belle detector on or near the $\Upsilon(nS)$ resonances, where $n=$1, 2, ..., 5. The cross sections for $e^+ e^- \to K^+ K^- J/\psi$ are at a few pb level and the average cross section for $e^+ e^- \to K_S^0K_S^0J/\psi$ is $1.8\pm 0.6 (\rm stat.)\pm 0.3 (\rm syst.)$~pb between 4.4 and 5.2~GeV. All of them are consistent with previously published results with improved precision. A search for resonant structures and associated intermediate states in the cross section of the process $e^+ e^- \to K^+ K^- J/\psi$ is performed., Comment: 14 pages, 7 figures

Abstract

We present a search for a non-Standard-Model invisible particle $X^0$ in the mass range $0.1\textrm{-}1.8 \,{\rm GeV}/{c^2}$ in $B^{+}\to e^{+} X^{0}$ and $B^{+}\to \mu^{+} X^{0}$ decays. The results are obtained from a $711~{\rm fb}^{-1}$ data sample that corresponds to $772 \times 10^{6} B\bar{B}$ pairs, collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB $e^+ e^-$ collider. One $B$ meson is fully reconstructed in a hadronic mode to determine the momentum of the lepton of the signal decay in the rest frame of the recoiling partner $B$ meson. We find no evidence of a signal and set upper limits on the order of $10^{-6}$., Comment: 8 pages, 4 figures, 3 tables

Abstract

We report results on the studies of the $e^+e^-\to B_s^{(*)}\bar{B}_s^{(*)}$ processes. The results are based on a $121.4$ fb$^{-1}$ data sample collected with the Belle detector at the center-of-mass energy near the $\Upsilon(10860)$ peak and $16.4$ fb$^{-1}$ of data collected at 19 energy points in the range from 10.77 to 11.02 GeV. We observe a clear $e^+e^-\to\Upsilon(10860)\to B_s^{(*)}\bar{B}_s^{(*)}$ signal, with no statistically significant signal of $e^+e^-\to \Upsilon(11020)\to B_s^{(*)}\bar{B}_s^{(*)}$. The relative production ratio of $B_s^*\bar{B}_s^*$, $B_s\bar{B}_s^{*}$, and $B_s\bar{B}_s$ final states at $\sqrt{s}=10.866$ GeV is measured to be $7:$ $0.856\pm0.106(stat.)\pm0.053(syst.):$ $0.645\pm0.094(stat.)^{+0.030}_{-0.033}(syst.)$. An angular analysis of the $B_s^*\bar{B}_s^*$ final state produced at the $\Upsilon(10860)$ peak is also performed., Comment: 22 page, 6 figures

Abstract

We report a search for $B^{0}\to \eta \eta $ with a data sample corresponding to an integrated luminosity of $698 \,{\rm fb}^{-1}$ containing $753 \times 10^{6}$ $B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. The branching fraction is measured to be $\mathcal{B}(B^{0} \to \eta \eta ) = (7.6^{+2.7 +1.4}_{-2.3 -1.6}) \times 10^{-7}$ at the level of 3.3 standard deviations above zero, which provides the first evidence for the decay $B^{0} \to \eta \eta$., Comment: 9 pages, 3 figures, ICHEP 2016

Abstract

We report the discovery of $\Xi_{c}(3055)^{0}$, observed by its decay into the final state $\Lambda D^{0}$, and present the first observation and evidence of the decays of $\Xi_c(3055)^{+}$ and $\Xi_c(3080)^{+}$ into $\Lambda D^{+}$. We also perform a combined analysis of the $\Lambda D^{+}$ with the $\Sigma_{c}^{++}K^{-}$ and $\Sigma_{c}^{\ast ++}K^{-}$ decay modes to measure the ratios of branching fractions, masses and widths with improved accuracy. We measure the ratios of branching fractions ${\cal B}(\Xi_{c}(3055)^{+} \to \Lambda D^{+})/{\cal B}(\Xi_{c}(3055)^{+} \to \Sigma_{c}^{++}K^{-})=5.09\pm1.01\pm0.76$, ${\cal B}(\Xi_{c}(3080)^{+} \to \Lambda D^{+})/{\cal B}(\Xi_{c}(3080)^{+} \to \Sigma_{c}^{++}K^{-})=1.29\pm0.30\pm0.15$, and ${\cal B}(\Xi_{c}(3080)^{+} \to \Sigma_{c}^{\ast ++}K^{-})/{\cal B}(\Xi_{c}(3080)^{+} \to \Sigma_{c}^{++}K^{-})=1.07\pm0.27\pm0.01$, where the uncertainties are statistical and systematic. The analysis is performed using a 980 fb$^{-1}$ data sample collected with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider., Comment: Submitted to PRD

Abstract

We have searched for the decay B0 -> phi gamma using the full Belle data set of 772 x 10^6 BBbar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB e+e- collider. No signal is observed, and we set an upper limit on the branching fraction of B(B0 -> phi gamma) < 1.0 x 10^{-7} at 90% confidence level. This is the most stringent limit on this decay mode to date., Comment: 13 pages, 2 figures, 1 table, submitted to Physical Review D (RC)

Abstract

The process $\gamma \gamma \to p \bar{p} K^+ K^-$ and its intermediate processes are measured for the first time using a 980~fb$^{-1}$ data sample collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. The production of $p \bar{p} K^+ K^-$ and a $\Lambda(1520)^0~(\bar{\Lambda}(1520)^0)$ signal in the $pK^-$~($\bar{p} K^+$) invariant mass spectrum are clearly observed. However, no evidence for an exotic baryon near 1540~MeV/$c^2$, denoted as $\Theta(1540)^0$~($\bar{\Theta}~(1540)^0$) or $\Theta(1540)^{++}$~($\Theta(1540)^{--}$), is seen in the $p K^-$~($\bar{p}K^+$) or $pK^+$~($\bar{p} K^-$) invariant mass spectra. Cross sections for $\gamma \gamma \to p \bar{p} K^+ K^-$, $\Lambda(1520)^0 \bar{p} K^+ +c.c.$ and the products $\sigma(\gamma \gamma \to \Theta(1540)^0 \bar{p} K^+ +c.c.)\BR(\Theta(1540)^0 \to p K^{-})$ and $\sigma(\gamma \gamma \to \Theta(1540)^{++} \bar{p} K^- +c.c.)\BR(\Theta(1540)^{++}\to p K^{+})$ are measured. We also determine upper limits on the products of the $\chi_{c0}$ and $\chi_{c2}$ two-photon decay widths and their branching fractions to $p \bar{p} K^+ K^-$ at the 90\% credibility level., Comment: 9 pages, 9 figures

Abstract

Regional cerebral blood flow (rCBF), cerebral metabolic rate of oxygen (rCMRO2), oxygen extraction fraction (rOEF), and cerebral blood volume (rCBV) were investigated using positron emission tomography (PET) in 16 patients with senile dementia of Alzheimer's type (SDAT), and compared with those of 6 nondemented and 3 demented patients with deep white matter high signal (DWMH) on T2-weighted MRI and 6 controls. rCBF, rCMRO2 and rCBV were determined using C15O2, 15O2 and C15O, respectively. rCBF and CMRO2 were significantly decreased in the frontal, parietal and temporal cortex (P < 0.05) in patients with SDAT, and showed a significant correlation with the severity of dementia (P < 0.05). In patients with DWMH rCBF was significantly decreased in the parietal cortex and in the frontal white matter in nondemented patients, and in the cerebral cortex and white matter of most regions studied in demented patients (P < 0.05), whereas rCMRO2 was significantly reduced in only the frontal and temporal cortex of demented patients (P < 0.05). rOEF was significantly increased in the parietal cortex of patients with SDAT and in the white matter of patients with SDAT or DWMH (P < 0.05), and the increase in the frontal white matter significantly paralleled the progression of dementia in patients with SDAT (P < 0.05). rCBV was significantly decreased in the parietal and temporal cortex of patients with SDAT (P < 0.05), but not in any areas of those with DWMH. These results suggest that rOEF is increased in both SDAT and patients with DWMH. The increase in rOEF in patients with SDAT may be accounted for by reduction in rCBV resulting from decreased activity in the vasodilatory cholinergic system, impairment of glucose metabolism and white matter changes; the rOEF increase in patients with DWMH suggests relative preservation of oxidative metabolism compared to disturbed perfusion.

Abstract

The $e^+e^- \to \pi^+ \pi^- \pi^0 \chi_{bJ}$ ($J=0,~1,~2$) processes are studied using a 118~fb$^{-1}$ data sample collected at a center-of-mass energy of 10.867 GeV, in the $\Upsilon(10860)$ energy range, with the Belle detector. The $\pi^+ \pi^- \pi^0 \chi_{b1}$, $\pi^+\pi^-\pi^0\chi_{b2}$, $\omega\chi_{b1}$ signals and the evidence of $\omega\chi_{b2}$ are observed for the first time and the cross sections are measured. No significant $\pi^+\pi^-\pi^0\chi_{b0}$ or $\omega\chi_{b0}$ signal is observed and 90\% confidence level upper limits on the cross sections for these two processes are obtained. In the $\pi^+\pi^-\pi^0$ invariant mass spectrum, significant non-$\omega$ signals are also observed. We search for the $X(3872)$-like state with a hidden $b\bar{b}$ component (named $X_b$) decaying into $\omega \Upsilon(1S)$; no significant signal is observed with a mass between $10.55$ and $10.65$ GeV/$c^2$., Comment: 7 pages, 3 figures, accepted for publication as a Letter in Physical Review Letters

The e+e-??+?-?0?bJ (J=0,1,2) processes are studied using a 118fb-1 data sample acquired with the Belle detector at a center-of-mass energy of 10.867 GeV. Unambiguous ?+?-?0?bJ (J=1,2), ??b1 signals are observed, and indication for ??b2 is seen, both for the first time, and the corresponding cross section measurements are presented. No significant ?+?-?0?b0 or ??b0 signals are observed, and 90% confidence level upper limits on the cross sections for these two processes are obtained. In the ?+?-?0 invariant mass spectrum, significant non-? signals are also observed. We search for the X(3872)-like state (named Xb) decaying into ??(1S); no significant signal is observed with a mass between 10.55 and 10.65GeV/c2. � 2014 American Physical Society.

Abstract

We report a search for charmless hadronic decays of neutral $B$ mesons to $��' K^{*}(892)^{0}$. The results are based on a 711fb$^{-1}$ data sample that contains $772\times 10^6 B\overline{B}$ pairs, collected at the $��(4S)$ resonance with the Belle detector at the KEKB asymmetric energy $e^+e^-$ collider. We observe the decay for the first time with a significance of 5.0 standard deviations and obtain its branching fraction ${\cal B}[B^0\to��' K^{*}(892)^{0}]=[2.6\pm0.7{\rm (stat)}\pm0.2{\rm (syst)}]\times 10^{-6}$. We also measure the $CP$ violating asymmetry as ${\cal A}_{CP}[B^0\to��' K^{*}(892)^{0}]=-0.22\pm0.29{\rm (stat)}\pm0.07{\rm syst}$., 11 pages, 2 figures, submitted PRD(RC)

Abstract

We report measurement of the cross section of $e^+e^-\to ��^+��^-��(2S)$ between 4.0 and $5.5 {\rm GeV}$, based on an analysis of initial state radiation events in a $980 \rm fb^{-1}$ data sample recorded with the Belle detector. The properties of the $Y(4360)$ and $Y(4660)$ states are determined. Fitting the mass spectrum of $��^+��^-��(2S)$ with two coherent Breit-Wigner functions, we find two solutions with identical mass and width but different couplings to electron-positron pairs: $M_{Y(4360)} = (4347\pm 6\pm 3) {\rm MeV}/c^2$, $��_{Y(4360)} = (103\pm 9\pm 5) {\rm MeV}$, $M_{Y(4660)} = (4652\pm10\pm 8) {\rm MeV}/c^2$, $��_{Y(4660)} = (68\pm 11\pm 1) \rm MeV$; and ${\cal{B}}[Y(4360)\to ��^+��^-��(2S)]\cdot ��_{Y(4360)}^{e^+e^-} = (10.9\pm 0.6\pm 0.7) \rm eV$ and ${\cal{B}}[Y(4660)\to ��^+��^-��(2S)]\cdot ��_{Y(4660)}^{e^+e^-} = (8.1\pm 1.1\pm 0.5) \rm eV$ for one solution; or ${\cal{B}}[Y(4360)\to ��^+��^-��(2S)]\cdot ��_{Y(4360)}^{e^+e^-} = (9.2\pm 0.6\pm 0.6) \rm eV$ and ${\cal{B}}[Y(4660)\to ��^+��^-��(2S)]\cdot ��_{Y(4660)}^{e^+e^-} = (2.0\pm 0.3\pm 0.2) \rm eV$ for the other. Here, the first errors are statistical and the second systematic. Evidence for a charged charmoniumlike structure at $4.05 {\rm GeV}/c^2$ is observed in the $��^{\pm}��(2S)$ intermediate state in the $Y(4360)$ decays., 21 pages, 12 figures

Abstract

We report results on studies of the e+e- annihilation into three-body Y(nS)pi+pi- (n=1,2,3) final states including measurements of cross sections and the full amplitude analysis. The cross sections measured at sqrt(s)=10.865 GeV and corrected for the initial state radiation are sigma(e+e-=>Y(1S)pi+pi-)=(2.27+-0.12+-0.14) pb, sigma(e+e-=>Y(2S)pi+pi-)=(4.07+-0.16+-0.45) pb, and sigma(e+e-=>Y(3S)pi+pi-)=(1.46+-0.09+-0.16) pb. Amplitude analysis of the three-body Y(nS)pi+pi- final states strongly favors I^G(J^P)=1^+(1^+) quantum-number assignments for the two bottomonium-like Zb+- states, recently observed in the Y(nS)pi+- and hb(mP)pi+- (m=1,2) decay channels. The results are obtained with a $121.4 1/fb data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. arXiv

Abstract

We report a measurement of D0-D?0 mixing parameters and a search for indirect CP violation through a time-dependent amplitude analysis of D0?KS0?+?- decays. The results are based on 921fb-1 of data accumulated with the Belle detector at the KEKB asymmetric-energy e+e- collider. Assuming CP conservation, we measure the mixing parameters x=(0.56�0.19- 0.09-0.09+0.03+0.06)% and y=(0.30�0.15-0.05-0.06+0.04+0.03)%, where the errors are statistical, experimental systematic, and systematic due to the amplitude model, respectively. With CP violation allowed, the parameters |q/p|=0.90-0.15-0.04-0.05+0.16+0.05+0.06 and arg(q/p)=(-6�11�3- 4+3)� are found to be consistent with conservation of CP symmetry in mixing and in the interference between mixing and decay, respectively. � 2014 American Physical Society.

Physical review / D 89, 072009 (2014). doi:10.1103/PhysRevD.89.072009, We report measurements of branching fractions of $\tau $ lepton decays to final states with a ${K}_{S}^{0}$ meson using a $669\text{}\text{}{\mathrm{fb}}^{-1}$ data sample accumulated with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{-}$ collider. The inclusive branching fraction is measured to be $\mathcal{B}\left({\tau }^{-}\to {K}_{S}^{0}{X}^{-}{\nu }_{\tau }\right)=\left(9.15±0.01±0.15\right)×1{0}^{-3}$, where ${X}^{-}$ can be anything; the exclusive branching fractions are $\mathcal{B}\left({\tau }^{-}\to {\pi }^{-}{K}_{S}^{0}{\nu }_{\tau }\right)=\left(4.16±0.01±0.08\right)×\phantom{\rule{0ex}{0ex}}1{0}^{-3}$, $\mathcal{B}\left({\tau }^{-}\to {K}^{-}{K}_{S}^{0}{\nu }_{\tau }\right)=\left(7.40±0.07±0.27\right)×1{0}^{-4}$, $\mathcal{B}\left({\tau }^{-}\to {\pi }^{-}{K}_{S}^{0}{\pi }^{0}{\nu }_{\tau }\right)=\left(1.93±0.02±0.07\right)×1{0}^{-3}$, $\mathcal{B}\left({\tau }^{-}\to {K}^{-}{K}_{S}^{0}{\pi }^{0}{\nu }_{\tau }\right)=\left(7.48±0.10±0.37\right)×1{0}^{-4}$, $\mathcal{B}\left({\tau }^{-}\to {\pi }^{-}{K}_{S}^{0}{K}_{S}^{0}{\nu }_{\tau }\right)=\left(2.33±0.03±0.09\right)×1{0}^{-4}$, $\mathcal{B}\left({\tau }^{-}\to {\pi }^{-}{K}_{S}^{0}{K}_{S}^{0}{\pi }^{0}{\nu }_{\tau }\right)=\left(2.00±0.22±0.20\right)×1{0}^{-5}$, where the first uncertainty is statistical and the second is systematic. For each mode, the accuracy is improved over that of pre-$B$-factory measurements by a factor ranging from five to ten. In ${\tau }^{-}\to {\pi }^{-}{K}_{S}^{0}{K}_{S}^{0}{\pi }^{0}{\nu }_{\tau }$ decays, clear signals for the intermediate states ${\tau }^{-}\to {\pi }^{-}{f}_{1}\left(1285\right){\nu }_{\tau }$ and ${\tau }^{-}\to {K}^{*-}{K}_{S}^{0}{\pi }^{0}{\nu }_{\tau }$ are observed., Published by American Physical Society, [S.l.]

Abstract

We report measurement of the cross section of $e^+e^-\to \pi^+\pi^-\psi(2S)$ between 4.0 and $5.5 {\rm GeV}$, based on an analysis of initial state radiation events in a $980 \rm fb^{-1}$ data sample recorded with the Belle detector. The properties of the $Y(4360)$ and $Y(4660)$ states are determined. Fitting the mass spectrum of $\pi^+\pi^-\psi(2S)$ with two coherent Breit-Wigner functions, we find two solutions with identical mass and width but different couplings to electron-positron pairs: $M_{Y(4360)} = (4347\pm 6\pm 3) {\rm MeV}/c^2$, $\Gamma_{Y(4360)} = (103\pm 9\pm 5) {\rm MeV}$, $M_{Y(4660)} = (4652\pm10\pm 8) {\rm MeV}/c^2$, $\Gamma_{Y(4660)} = (68\pm 11\pm 1) \rm MeV$; and ${\cal{B}}[Y(4360)\to \pi^+\pi^-\psi(2S)]\cdot \Gamma_{Y(4360)}^{e^+e^-} = (10.9\pm 0.6\pm 0.7) \rm eV$ and ${\cal{B}}[Y(4660)\to \pi^+\pi^-\psi(2S)]\cdot \Gamma_{Y(4660)}^{e^+e^-} = (8.1\pm 1.1\pm 0.5) \rm eV$ for one solution; or ${\cal{B}}[Y(4360)\to \pi^+\pi^-\psi(2S)]\cdot \Gamma_{Y(4360)}^{e^+e^-} = (9.2\pm 0.6\pm 0.6) \rm eV$ and ${\cal{B}}[Y(4660)\to \pi^+\pi^-\psi(2S)]\cdot \Gamma_{Y(4660)}^{e^+e^-} = (2.0\pm 0.3\pm 0.2) \rm eV$ for the other. Here, the first errors are statistical and the second systematic. Evidence for a charged charmoniumlike structure at $4.05 {\rm GeV}/c^2$ is observed in the $\pi^{\pm}\psi(2S)$ intermediate state in the $Y(4360)$ decays., Comment: 21 pages, 12 figures

Abstract

We present a measurement of the branching fractions and charge-parity-(CP-)violating parameters in B??K decays. The results are obtained from the final data sample containing 772�106 BB? pairs collected at the ?(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain the branching fractions B(B0??K0)=(4.5�0.4(stat)�0.3(syst))�10-6, B(B+??K+)=(6.8�0.4(stat)�0.4(syst))�10-6 which are in agreement with their respective current world averages. For the CP-violating parameters, we obtain A?KS0=-0.36�0.19(stat)�0. 05(syst),S?KS0=+0.91�0.32(stat)�0.05(syst),A?K+=-0. 03�0.04(stat)�0.01(syst), where A and S represent the direct and mixing-induced CP asymmetry, respectively. We find no evidence of CP violation in the decay channel B+??K+; however, we obtain the first evidence of CP violation in the B0??KS0 decay channel at the level of 3.1 standard deviations. � 2014 American Physical Society.

Abstract

We find evidence for the semileptonic baryonic decay B−→pp¯ℓ−ν¯ℓ ( ℓ=e , μ ), based on a data sample of 772 million BB¯ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy electron-positron collider. A neural-network based hadronic B -meson tagging method is used in this study. The branching fraction of B−→pp¯ℓ−ν¯ℓ is measured to be (5.8−2.1+2.4(stat)±0.9(syst))×10−6 with a significance of 3.2σ , where lepton universality is assumed. We also estimate the corresponding upper limit: B(B−→pp¯ℓ−ν¯ℓ)

Abstract

We present a measurement of the time-dependent CP violation parameters in B$^{0}$ → η′K$^{0}$ decays. The measurement is based on the full data sample containing 772 × 10$^{6}$ $ B\overline{B} $ pairs collected at the Υ(4S) resonance using the Belle detector at the KEKB asymmetric-energy e$^{+}$ e$^{−}$ collider. The measured values of the mixing-induced and direct CP violation parameters are: $ \sin\ 2{\phi}_1^{\mathrm{eff}}=+0.68\pm 0.07\pm 0.03, $ $ {\mathcal{A}}_{{{{\eta}}_{\prime}}_{K^0}}=+0.03\pm 0.05\pm 0.04, $

Abstract

We report measurements of branching fractions of ? lepton decays to final states with a KS0 meson using a 669fb-1 data sample accumulated with the Belle detector at the KEKB asymmetric-energy e+e- collider. The inclusive branching fraction is measured to be B(?-?KS0X-??)=(9. 15�0.01�0.15)�10-3, where X- can be anything; the exclusive branching fractions are B(?-??-KS0??)=(4.16�0. 01�0.08)�10-3, B(?-?K-KS0??)=(7.40�0. 07�0.27)�10-4, B(?-??-KS0?0??)=(1. 93�0.02�0.07)�10-3, B(?-?K-KS0?0??)=(7. 48�0.10�0.37)�10-4, B(?-??-KS0KS0??)=(2. 33�0.03�0.09)�10-4, B(?-??-KS0KS0?0??) =(2.00�0.22�0.20)�10-5, where the first uncertainty is statistical and the second is systematic. For each mode, the accuracy is improved over that of pre-B-factory measurements by a factor ranging from five to ten. In ?-??-KS0KS0?0?? decays, clear signals for the intermediate states ?-??-f1(1285)?? and ?-?K*- KS0?0?? are observed. � 2014 American Physical Society.

Abstract

We report a measurement of ${D^{0}}$-${\overline{D}{}^{0}}$ mixing parameters and a search for indirect $CP$ violation through a time-dependent amplitude analysis of ${D^0\to K_S^0��^+��^-}$ decays. The results are based on 921~fb$^{-1}$ of data accumulated with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. Assuming $CP$ conservation, we measure the mixing parameters $x=(0.56\pm0.19^{+0.03}_{-0.09}{^{+0.06}_{-0.09}})\%$ and $y=(0.30\pm0.15^{+0.04}_{-0.05}{^{+0.03}_{-0.06})}\%$, where the errors are statistical, experimental systematic, and systematic due to the amplitude model, respectively. With $CP$ violation allowed, the parameters $|q/p|=0.90^{+0.16}_{-0.15}{^{+0.05}_{-0.04}}{^{+0.06}_{-0.05}}$ and $\arg(q/p)=(-6\pm11{\pm3}{^{+3}_{-4}})^{\circ}$ are found to be consistent with conservation of $CP$ symmetry in mixing and in the interference between mixing and decay, respectively., submitted to PRD(RC)

Abstract

We report the first observation of $B^0 \to X(3872) (K^{+}\pi^{-})$ and evidence for $B^+ \to X(3872) (K^{0}\pi^{+})$. We measure the product of branching fractions for the former to be ${\cal B}(B^0 \to X(3872) (K^+ \pi^-)) \times {\cal B}(X(3872) \to J/\psi \pi^+ \pi^-) = (7.9 \pm 1.3(\mbox{stat.})\pm 0.4(\mbox{syst.})) \times 10^{-6}$ and find that $B^{0}\to X(3872) K^{*}(892)^{0}$ does not dominate the $B^{0}\to X(3872)K^{+}\pi^{-}$ decay mode. We also measure ${\cal B}(B^+ \to X(3872) (K^0 \pi^+)) \times {\cal B}(X(3872) \to J/\psi \pi^+ \pi^-) = (10.6 \pm 3.0(\mbox{stat.}) \pm 0.9(\mbox{syst.})) \times 10^{-6}$. This study is based on the full data sample of 711~fb$^{-1}$ ($772\times 10^6 B\bar B$ pairs) collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB collider., Comment: 7 pages, 3 figures

Abstract

We present a measurement of the time-dependent $CP$ violation parameters in $B^0\to��'K^0$ decays. The measurement is based on the full data sample containing $772\times 10^6$ $B\bar{B}$ pairs collected at the $��(4S)$ resonance using the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. The measured values of the mixing-induced and direct $CP$ violation parameters are: \begin{align} \sin 2 ��^{\rm eff}_1 &= +0.68\pm 0.07 \pm 0.03, \nonumber \\ \mathcal{A}_{��'K^0} &= +0.03\pm 0.05\pm 0.04, \nonumber \end{align} where the first uncertainty is statistical and the second is systematic. The values obtained are the most accurate to date. Furthermore, these results are consistent with our previous measurements and with the world-average value of $\sin 2��_1$ measured in $B^0\to J/��K^0$ decays.}, 15 pages, 3 figures

Abstract

We search for the decay $B_{s}^{0}\rightarrow����$ and measure the branching fraction for $B_{s}^{0}\rightarrow����$ using 121.4~$\textrm{fb}^{-1}$ of data collected at the $��(\mathrm{5}S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. The $B_{s}^{0}\rightarrow����$ branching fraction is measured to be $(3.6 \pm 0.5 (\mathrm{stat.}) \pm 0.3 (\mathrm{syst.}) \pm 0.6 (f_{s})) \times 10^{-5}$, where $f_{s}$ is the fraction of $B_{s}^{(*)}\bar{B}_{s}^{(*)}$ in $b\bar{b}$ events. Our result is in good agreement with the theoretical predictions as well as with a recent measurement from LHCb. We observe no statistically significant signal for the decay $B_{s}^{0}\rightarrow����$ and set a $90\%$ confidence-level upper limit on its branching fraction at $ 3.1 \times 10^{-6}$. This constitutes a significant improvement over the previous result., 6 pages, 3 figures

Abstract

The $e^+e^- \to ��^+ ��^- ��^0 ��_{bJ}$ ($J=0,~1,~2$) processes are studied using a 118~fb$^{-1}$ data sample collected at a center-of-mass energy of 10.867 GeV, in the $��(10860)$ energy range, with the Belle detector. The $��^+ ��^- ��^0 ��_{b1}$, $��^+��^-��^0��_{b2}$, $����_{b1}$ signals and the evidence of $����_{b2}$ are observed for the first time and the cross sections are measured. No significant $��^+��^-��^0��_{b0}$ or $����_{b0}$ signal is observed and 90\% confidence level upper limits on the cross sections for these two processes are obtained. In the $��^+��^-��^0$ invariant mass spectrum, significant non-$��$ signals are also observed. We search for the $X(3872)$-like state with a hidden $b\bar{b}$ component (named $X_b$) decaying into $����(1S)$; no significant signal is observed with a mass between $10.55$ and $10.65$ GeV/$c^2$., 7 pages, 3 figures, accepted for publication as a Letter in Physical Review Letters

Abstract

We present a study of the branching fraction of the decay B0??0?0 and the fraction of longitudinally polarized ?0 mesons in this decay. The results are obtained from the final data sample containing 772�106 BB? pairs collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find 166�59 B0??0?0 events (including systematic uncertainties), corresponding to a branching fraction of B(B0??0?0)=(1.02�0.30(stat) �0.15(syst))�10-6 with a significance of 3.4 standard deviations and a longitudinal polarization fraction fL=0.21-0.22+0.18(stat)�0. 15(syst). We use the longitudinal polarization fraction to determine the Cabibbo-Kobayashi-Maskawa matrix angle ?2=(84.9�13.5)� through an isospin analysis in the B??? system. We furthermore find 125�41 B0?f0?0 events, corresponding to B(B0?f0?0) �B(f0??+?-)=(0.78�0.22(stat)�0.11(syst)) �10-6, with a significance of 3.1 standard deviations. We find no other significant contribution with the same final state, and set upper limits at 90% confidence level on the (product) branching fractions, B(B0??+?- ?+?-)

Abstract

Made available in DSpace on 2022-04-29T07:14:51Z (GMT). No. of bitstreams: 0 Previous issue date: 2014-01-01 Based on traditional uses and on previous pharmacological assays, the ethanol leaf extract of Plinia edulis and its fractions were evaluated in vivo for gastroprotection in HCl/ethanol induced ulcers. In addition, due to our ulcerative model, the antioxidant activities of the polar fractions of the extract were analyzed by the DPPH method. The ethanol extract showed significant antiulcer activity in rats at doses of 100 mg/kg p.o. and was more active than the reference drug lansoprazole at 30 mg/kg. Among the fractions obtained by solvent partition, the hexane fraction was the most effective (100 mg/kg p.o.), but was not as effective as the original extract. The chromatographic procedures for the hexane fraction yielded β-amyrin, lupeol, ursolic acid, maslinic acid, and corosolic acid; the ethyl acetate fraction yielded gallic acid, quercitrin, myricitrin and quercetin. The ursolic acid reduced the injurious area at a 50 mg/kg dose p.o., but the antiulcer activity was not significant in our model. The polar fractions exhibited prominent antioxidant activity and high contents of phenolic compounds. These results suggest that the promising gastroprotective effects of aqueous ethanol extract from P. edulis leaves could be due to the mixture of triterpenes and flavonoids.

Abstract

The cross sections of the processes e+e-?K+K-J/? and KS0KS0J/? are measured via initial state radiation at center-of-mass energies between the threshold and 6.0 GeV using a data sample of 980fb-1 collected with the Belle detector on or near the ?(nS) resonances, where n=1,2,...,5. The cross sections for e+e-?K+K-J/? are at a few pb level and the average cross section for e+e-?KS0KS0J/? is 1.8�0.6(stat)�0.3(syst)pb between 4.4 and 5.2 GeV. All of them are consistent with previously published results with improved precision. A search for resonant structures and associated intermediate states in the cross section of the process e+e-?K+K-J/? is performed. � 2014 American Physical Society.

Abstract

We report the first measurement of the lepton forward-backward asymmetry ${\cal A}_{\rm FB}$ for the inclusive electroweak penguin process $B \rightarrow X_s \ell^+ \ell^-$ as a function of $q^2=M_{\ell^+\ell^-}^2c^2$, where $\ell$ is an electron or a muon and $X_s$ is a hadronic recoil system with an $s$ quark. The results are based on a data sample containing $772\times10^6$ $B\bar{B}$ pairs recorded at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB $e^+ e^-$ collider. For $q^2 > 10.2$ GeV$^2$/$c^2$, ${\cal A}_{\rm FB} < 0$ is excluded at the 2.3$\sigma$ level, where $\sigma$ is the standard deviation. For $q^2 < 4.3$ GeV$^2$/$c^2$, the result is within 1.8$\sigma$ of the theoretical expectation.

Abstract

We report a search for charmless hadronic decays of neutral B mesons to ??K?(892)0. The results are based on a 711fb-1 data sample that contains 772�106BB� pairs, collected at the (4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. We observe the decay for the first time with a significance of 5.0 standard deviations and obtain its branching fraction B[B0???K?(892)0]=[2.6�0.7(stat)�0.2(syst)]�10-6. We also measure the CP-violating asymmetry as ACP[B0???K?(892)0]=-0.22�0.29(stat)�0.07(syst). � 2014 American Physical Society.

Abstract

We present a search for the rare leptonic decays $B^+ \to e^+ \nu_e$ and $B^+ \to \mu^+ \nu_\mu$, using the full $\Upsilon(4S)$ data sample of $772\times 10^6$ $B\bar{B}$ pairs collected with the Belle detector at the $\small\textbf{KEKB}$ asymmetric-energy $e^+ e^-$ collider. One of the $B$ mesons from the $\Upsilon(4S) \to B\bar{B}$ decay is fully reconstructed in a hadronic mode, while the recoiling side is analyzed for the signal decay. We find no evidence of a signal in any of the decay modes. Upper limits of the corresponding branching fractions are determined as ${\cal B}(B^+ \to e^+ \nu_e)

Abstract

We report results on studies of the e+e- annihilation into three-body Y(nS)pi+pi- (n=1,2,3) final states including measurements of cross sections and the full amplitude analysis. The cross sections measured at sqrt(s)=10.865 GeV and corrected for the initial state radiation are sigma(e+e-=>Y(1S)pi+pi-)=(2.27+-0.12+-0.14) pb, sigma(e+e-=>Y(2S)pi+pi-)=(4.07+-0.16+-0.45) pb, and sigma(e+e-=>Y(3S)pi+pi-)=(1.46+-0.09+-0.16) pb. Amplitude analysis of the three-body Y(nS)pi+pi- final states strongly favors I^G(J^P)=1^+(1^+) quantum-number assignments for the two bottomonium-like Zb+- states, recently observed in the Y(nS)pi+- and hb(mP)pi+- (m=1,2) decay channels. The results are obtained with a $121.4 1/fb data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider., 15 pages, 6 tables, 9 figures. To be submitted to Phys. Rev. D
