Abstract

Using 24 million $\psi' \equiv \psi(2S)$ decays in CLEO-c, we have searched for higher multipole admixtures in electric-dipole-dominated radiative transitions in charmonia. We find good agreement between our data and theoretical predictions for magnetic quadrupole (M2) amplitudes in the transitions $\psi' \to \gamma \chi_{c1,2}$ and $\chi_{c1,2} \to \gamma J/\psi$, in striking contrast to some previous measurements. Let $b_2^J$ and $a_2^J$ denote the normalized M2 amplitudes in the respective aforementioned decays, where the superscript $J$ refers to the angular momentum of the $\chi_{cJ}$. By performing unbinned maximum likelihood fits to full five-parameter angular distributions, we determine the ratios $a_2^{J=1}/a_2^{J=2} = 0.67^{+0.19}_{-0.13}$ and $a_2^{J=1}/b_2^{J=1} = -2.27^{+0.57}_{-0.99}$, where the theoretical predictions are independent of the charmed quark magnetic moment and are $a_2^{J=1}/a_2^{J=2} = 0.676 \pm 0.071$ and $a_2^{J=1}/b_2^{J=1} = -2.27 \pm 0.16$., Comment: 32 pages, 7 figures, acceptance update

Abstract

Using e+e- collision data taken with the CLEO-c detector at the Cornell Electron Storage Ring, we have investigated the direct photon spectrum in the decay ψ(2S)→γgg. We determine the ratio of the inclusive direct photon decay rate to that of the dominant three-gluon decay rate ψ(2S)→ggg (Rγ≡⌈Γgg(γgg)/⌈(ggg)) to be Rγ(zγ>0.4)=0.070±0.002±0.019±0.011, with zγ defined as the scaled photon energy relative to the beam energy. The errors shown are statistical, systematic, and that due to the uncertainty in the input branching fractions used to extract the ratio, respectively. © 2009 The American Physical Society.

Abstract

We measure the absolute branching fractions of $\Ds$ semileptonic decays where the hadron in the final state is one of $\phi$, $\eta$, $\etap$, $\Ks$, $\Kstar$, and $f_0$, using $2.8 \times 10^5$ $\epm \to \Ds\Dsstar$ decays collected in the CLEO-c detector at a center-of-mass energy close to 4170 MeV. We obtain ${\cal B}(\Dsp\to \phi e^+ \nu_e) =(2.29\pm 0.37 \pm 0.11)$%, ${\cal B}(\Dsp\to \eta e^+ \nu_e) =(2.48 \pm 0.29 \pm 0.13)$%, ${\cal B}(\Dsp\to \etap e^+ \nu_e) =(0.91 \pm 0.33 \pm 0.05)$%, where the first uncertainties are statistical and the second are systematic. We also obtain ${\cal B}(\Dsp\to K^0 e^+ \nu_e) =(0.37\pm 0.10 \pm 0.02)$%, and ${\cal B}(\Dsp\to K^{\star 0} e^+ \nu_e) =(0.18 \pm 0.07 \pm 0.01)$%, which are the first measurements of Cabibbo suppressed exclusive $\Ds$ semileptonic decays, and, ${\cal B}(\Dsp\to f_0 e^+ \nu_e) \times {\cal B}(f_0 \to \pip\pim) =(0.13\pm 0.04 \pm 0.01)$%. This is the first direct evidence of a semileptonic decay including a scalar meson in the final state., Comment: 10 pages, 2 figures, revised version, improved figures and added text

Abstract

Using the entire CLEO-c ψ(3770)→DD̄ event sample, corresponding to an integrated luminosity of 818pb-1 and approximately 5.4×106 DD̄ events, we present a study of the decays D0→π-e+νe, D0→K-e+νe, D+→π0e+νe, and D+→K̄0e+νe. Via a tagged analysis technique, in which one D is fully reconstructed in a hadronic mode, partial rates for semileptonic decays by the other D are measured in several q2 bins. We fit these rates using several form factor parametrizations and report the results, including form factor shape parameters and the branching fractions B(D0→π-e+νe)=(0.288±0. 008±0.003)%, B(D0→K-e+νe)=(3.50±0.03±0.04)%, B(D+→π0e+νe)=(0.405±0.016±0.009)%, and B(D+→K̄0e+νe)=(8.83±0.10±0.20)%, where the first uncertainties are statistical and the second are systematic. Taking input from lattice quantum chromodynamics, we also find |Vcd|=0.234±0.007±0. 002±0.025 and |Vcs|=0.985±0.009±0.006±0.103, where the third uncertainties are from lattice quantum chromodynamics. © 2009 The American Physical Society.

Abstract

We examine e+e-→Ds-Ds*+ and Ds*-Ds+ interactions at 4170 MeV using the CLEO-c detector in order to measure the decay constant fDs+ with good precision. Previously our measurements were substantially higher than the most precise lattice based QCD calculation of (241± 3)MeV. Here we use the Ds+→+ν channel, where the + designates either a μ+ or a τ+, when the τ+→π+ν̄. Analyzing both modes independently, we determine B(Ds+→μ+ν)=( 0.565±0.045±0.017)%, and B(Ds+→τ+ν)=(6.42±0.81± 0.18)%. We also analyze them simultaneously to find an effective value of Beff(Ds+→μ+ν)=(0.591± 0.037±0.018)% and fDs+=( 263.3±8.2±3.9)MeV. Combining with the CLEO-c value determined independently using Ds+→τ+ν, τ+→e+νν̄ decays, we extract fDs+=( 259.5±6.6±3.1)MeV. Combining with our previous determination of B(D+→μ+ν), we extract the ratio fDs+/fD+=1.26±0.06±0.02. No evidence is found for a CP asymmetry between Γ(Ds+→μ+ν) and Γ(Ds-→μ-ν); specifically the fractional difference in rates is measured to be (4.8±6.1)%. Finally, we find B(Ds+→e+ν)

Abstract

Using data taken with the CLEO-c detector at the Cornell Electron Storage Ring, we have investigated the direct-photon momentum spectrum in the decay J/{psi}(1S){yields}{gamma}gg, via the ''tagged'' process: e{sup +}e{sup -}{yields}{psi}(2S); {psi}(2S){yields}J/{psi}{pi}{sup +}{pi}{sup -}; J/{psi}{yields}{gamma}+X. Including contributions from two-body radiative decay processes, we find the ratio of the inclusive direct-photon branching fraction to that of the dominant three-gluon branching fraction [R{sub {gamma}}=B(gg{gamma})/B(ggg)] to be R{sub {gamma}}=0.137{+-}0.001{+-}0.016{+-}0.004, where the errors shown are statistical, systematic, and the model-dependent uncertainty related to the extrapolation to zero photon energy. The shape of the scaled photon energy spectrum in J/{psi}{yields}gg{gamma} is observed to be very similar to that of {upsilon}{yields}gg{gamma}. The R{sub {gamma}} value obtained is roughly consistent with that expected by a simple quark-charge scaling [R{sub {gamma}}{approx}(q{sub c}/q{sub b}){sup 2}] of the value determined at the {upsilon}(1S), but somewhat higher than the value expected from the running of the strong coupling constant.

Abstract

Using data collected by the CLEO detector in the Upsilon(4S) region, we report new measurements of the exclusive decays of B mesons into final states of the type Lambda_c^+ p-bar n(pi), where n=0,1,2,3. We find signals in modes with one, two and three pions and an upper limit for the two body decay Lambda_c^+ pbar. We also make the first measurements of exclusive decays of B mesons to Sigma_c p-bar n(pi), where n=0,1,2. We find signals in modes with one and two pions and an upper limit for the two body decay Sigma_c p-bar. Measurements of these modes shed light on the mechanisms involved in B decays to baryons., Comment: 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS, submitted to PRL

Abstract

The ratio of charged and neutral B meson production at the γ(4S), f +-/f 00, is measured through the decays B̄→D*ℓ -ν̄ ℓ, reconstructed using a partial reconstruction method where the D* is detected only through a pion daughter from the decay D*→Dπ. Using data collected by the CLEO II detector, the charged and neutral B decays are measured in such a way that their ratio is independent of the decay model, limited mainly by the uncertainty in the relative efficiency for detecting neutral and charged pions. This measurement yields the ratio of production fractions times the ratio of semileptonic branching fractions, f +-b +/f 00b 0. Assuming that b +/b 0 is equal to the lifetime ratio τ +/τ 0 and using the world average value of τ +/τ 0 as input, we obtain f +-/f 00= 1.058±0.084±0.136. © 2002 The American Physical Society.

Abstract

Using data recorded by the CLEO II and CLEO II.V detector configurations at CESR, we report new measurements of the masses of the ∑c++ and ∑c0 charmed baryons, and the first measurements of their intrinsic widths. We find M(∑c++)-M(Λc+) =167.4±0.1±0.2 MeV, Γ(∑c++)=2.3±0.2±0.3 MeV, and M(∑c0) -M(Λc+)=167.2±0.1±0.2 MeV, Γ(∑c0)=2.5±0.2±0.3 MeV, where the uncertainties are statistical and systematic, respectively.

Abstract

Continuing our studies of radiative Υ decays, we report on a search for Υ→γη and fj(2220) in 61.3 pb-1 of e+e- data taken with the CLEO II detector at the Cornell Electron Storage Ring. For the γη search the three decays of the η meson to π+ π- π0, π0 π0 π0, and γγ were investigated. We found no candidate events in the (3 π)0 modes and no significant excess over expected backgrounds in the γγ mode to set a limit on the branching fraction of B(Y→γη)< 2.1 × 10-5 at 90% C.L. The three charged two-body final states hh̄(h = π+, K+, p) were investigated for fj(2220) production, with one, one, and two events found, respectively. Limits at 90% C.L. of B(Υ→γfj) × B(fj→hh̄) ∼ 1.5 × 10-5 have been set for each of these modes. We compare our results to measurements of other radiative Υ decays, to measurements of radiative J/ψ decays, and to theoretical predictions.

Abstract

We present new measurements of branching fractions for the color-favored decays B + → D 0π - and B̄ 0 → D +π -. Using 9.67×10 6 BB̄ pairs collected with the CLEO detector, we obtain the branching fractions Β(B - → D 0π - = (49.7±1.2±2.9±2.2)×10 4 and Β(B̄ 0 → D +π -) = (26.8±1.2±2.4±1.2)×10 -4. The first error is statistical, the second is systematic, and the third is due to the experimental uncertainty on the production ratio of charged and neutral B mesons in Y(4S) decays. These results, together with the current world average for the color-suppressed branching fraction Β(B̄ + → D 0π 0), are used to determine the cosine of the strong phase difference δ I between the I = 1/2 and I=3/2 isospin amplitudes. We find cos δ I = 0.863 -0.023-0.035-0.030+0.024+0.036+0.038, and obtain a 90% confidence interval of 16.5° < δ I < 38.1°. This nonzero value of δ I suggests the presence of final state interactions in the D π system. © 2002 The American Physical Society.
