Abstract

The reaction $e^+e^−→e^+e^−π^0π^0$ has been analyzed using 97pb$^{−1}$ of data taken with the Crystal Ball detector at the DESY $e^−e^+$ storage ring DORIS II at beam energies around 5.3 GeV. For the first time we have measured the cross section for $γγ→π^0π^0$ for π0π0 mvariant masses ranging from threshold to about 2 GeV. We measure an approximately flat cross section of about 10 nb for W=$mπ^0π^0

Abstract

7 pp. (1990)., We have searched for axion and light Higgs boson production in the channel $ϒ (1S)$ → $(a^0 or h^0) + γ$, where the non-interacting axion a0 and the Higgs boson $h^0$ do not decay in the detector. We find no evidence for an axion and give an upper limit,$ Br(ϒ (1S) → a^0γ) < 4.0 × 10^{−5} (90% CL)$, for long-lived axions. Combining our limit with the previous search in J/ψ decays, we are able to rule out the axion in the standard model with first order QCD corrections. Our $ϒ (1S)$ data also rule out a Higgs boson with mass mh < 86 MeV.

19. Experimental upper limits for the hadronic transitions Υ(2 S)→ηΥ(1 S) and Υ(2 S)→πΥ(1 S).

Abstract

Using the Crystal Ball detector at the ee storage ring DORIS-II, we have searched for the hadronic transitions Υ(2 S)→ηΥ(1 S) and Υ(2 S)→πΥ(1 S) in exclusive decays where the Υ(1 S) decays into an ee or a µ µ pair and the η and π are detected by their decay modes η→γγ, η→ γγ and π→ γγ. From the number of observed events we derive, after consideration of possible background sources, upper limits on the branching ratios B(Υ(2 S)→ηΥ(1 S))<0.7% and B(Υ(2S)→πΥ(1 S))<0.8% at the 90% confidence level.

Abstract

The Crystal Ball detector at the e e storage ring DORIS-II has been used to search for radiative B meson decays, especially of the type b→ sγ. No monoenergetic γ-lines have been found in the inclusive photon spectrum from У(4 S) decays, and upper limits are obtained for radiative decays of B mesons to various strange mesons and to the D. Integrating the photon spectrum over the corresponding energy range, we find at 90% confidence level for the mass range 892 MeV ≦ M≦2045 MeV. [ABSTRACT FROM AUTHOR]

Abstract

Using the Crystal Ball detector at the e e storage ring DORIS II, we have measured the branching fraction to muon pairs B of the Υ(1 S) and Υ(2 S) resonances and for the first time the product of the muonic partial width Γ and the branching fraction to electrons B for both resonances. We obtain and Inserting the present world average value of B(1 S)=(2.52±0.17)%, we determine the muonic partial width of the Υ(1 S) as In addition, we present the first indication of the expected interference between μ-pair production in the continuum and in Υ(1 S) decays.

Abstract

The Crystal Ball detector has been used at the DORIS II storage ring at DESY to study the reaction γγ→ π π π in the π π π invariant mass range from 850 MeV/c to 2600 MeV/c. An enhancement around 1750 MeV/c is attributed to the π(1670) resonance. The observed π π invariant mass distribution and the π angular distributions are consistent with those expected for the decay chain π→ π f(1270)→ π π π. From our measurements we find the following resonance parameters: two photon partial width $$\Gamma _{\pi _2 }^{\gamma \gamma } = (1.41 \pm 0.23 \pm 0.28)keV$$ , mass M( π)=(1742±31±49)MeV/c. and total width $$\Gamma _{\pi _2 }^{tot} = (236 \pm 49 \pm 36)MeV$$ .

Abstract

The production of J/ψ in B meson decays has been measured on the Γ(4 S) resonance using the Crystal Ball detector at the e e storage ring DORIS II. The J/ψ is identified by its e e decay mode. We obtain a branching ratio of BR( B→J/ψ X)=(1.12±0.33±0.25)% in good agreement with theoretical predictions based on color suppression. The J/ψ momentum distribution is observed to be peaked at high values. This implies a substantial contribution from direct B meson decays to the J/ψ. In addition upper limits on J/ψ production in Γ(1 S) and Γ(2 S) decays and in continuum processes are determined. [ABSTRACT FROM AUTHOR]

Abstract

We have searched for radiative decays of the ϒ(1 S) resonance, ϒ(1 S)→γ X, where X is one of the mesons η, η′ f (1270), f (1720), or a narrow resonance with mass less than 3 GeV/c which decays into either ππ or ηη. The mesons are identified in their all-neutral decay modes. Since we do not find any such decays, we calculate upper limits on the corresponding branching ratios. These limits are compared to theoretical predictions and to the corresponding branching ratios measured in radiative J/Ψ decays. [ABSTRACT FROM AUTHOR]

Abstract

The Crystal Ball detector has been used at the DORIS II storage ring at DESY to study the reactionγγ→π0π0π0 in theπ0π0π0 invariant mass range from 850 MeV/c2 to 2600 MeV/c2. An enhancement around 1750 MeV/c2 is attributed to theπ2(1670) resonance. The observedπ0π0 invariant mass distribution and theπ0 angular distributions are consistent with those expected for the decay chainπ2→π0f2(1270)→π0π0π0. From our measurements we find the following resonance parameters: two photon partial width ", massM(π2)=(1742±31±49)MeV/c2. and total width ".

Abstract

Using the Crystal Ball detector at thee+e− storage ring DORIS-II, we have searched for the hadronic transitions Υ(2S)→ηΥ(1S) and Υ(2S)→π0Υ(1S) in exclusive decays where the Υ(1S) decays into ane+e− or aµ+µ- pair and the η and π0 are detected by their decay modes η→γγ, η→γγ and π0→γγ. From the number of observed events we derive, after consideration of possible background sources, upper limits on the branching ratiosB(Υ(2S)→ηΥ(1S))<0.7% andB(Υ(2S)→π0Υ(1S))<0.8% at the 90% confidence level.

Abstract

The Crystal Ball detector has been used at the DORIS II storage ring at DESY to study the reaction e+e−→e+e−γ*γ*→e+e−γγ, where X is a narrow resonance with mass between 100 and 3000 MeV. Formation of π0, η, and η’ mesons is observed, and the following meson partial widths are obtained: Γπ0Γ0→γγ=7.7±0.5±0.5 eV, Γη−γγ=0.514±0.017±0.035 keV, and Γη’→γγ=4.7±0.5±0.5 keV. No other narrow resonances are observed, and upper limits are given for the product ΓX→γγBX→γγ. .AE

Abstract

Angular correlations in the cascade reaction e+e−→Υ(2S)→γχb, χb→γΥ, Υ→μ+μ− or Υ→e+e−, have been used for the first time to investigate the spins of the χb states. The results support the χb spins predicted by the potential models of heavy quarkonia.
