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.

Abstract

The Crystal Ball detector at the e e storage ring DORIS II has been used to analyze exclusive semileptonic decays of B mesons produced at γ(4 S) energies. The decay B→evD has been observed with a branching ratio of (7.0±1.8±1.4)% using the π°D decay mode of the D. In addition we have searched for the exclusive semileptonic decay B→ e vπ. We find an upper limit on B→ e vπ of 0.22% at the 90% CL. [ABSTRACT FROM AUTHOR]

21. The electron spectrum from B meson decays.

Abstract

The Crystal Ball Collaboration has measured the energy spectrum of electrons from semileptonic B meson decays at the e e storage ring DORIS II. Branching ratios and weak mixing angles of the Kobayashi-Maskawa matrix are determined using several models for the hadronic matrix elements. We obtain the branching ratio for semileptonic. B decays to charmed states BR( B→evX)=(11.7±0.4±1.0)%. Our result for the corresponding Kobayashi-Maskawa matrix element is | V|=0.052±0.006. The model dependence of both results is included in the error. We have not observed semileptonic B decays to non-charmed mesons. Analyzing the measured electron spectrum above 2.4 GeV, where no b→c decays contribute, we find BR( B→evX)/ BR( B→evX)<6.5% at the 90% confidence level. This corresponds to an upper limit | V/ V|<0.21. [ABSTRACT FROM AUTHOR]

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

Using the Crystal Ball detector operating at the DORIS II storage ring we have measured the leptonic partial widthsГee of the Υ(1S) and Υ(2S) resonances. We find $$\Gamma _{ee} (\Upsilon (1S)) = 1.34 \pm 0.03 \pm 0.06keV$$ and $$\Gamma _{ee} (\Upsilon (2S)) = 0.56 \pm 0.04 \pm 0.02keV.$$ The effect onГee of applying different prescriptions for radiative corrections is discussed. We also measureR, the ratio of non-resonant hadronic cross section to the Born cross section of μ pair production, at c.m. energyW=9.39 GeV to beR=3.48±0.04±0.16.

We find an upper limit onB±→e±vπ0 of 0.22% at the 90% CL.

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.

Abstract

Physical review / D 36(9), 2633 - 2640 (1987). doi:10.1103/PhysRevD.36.2633, The reaction e+e−→e+e−ηπ0π0 has been observed with the Crystal Ball detector at the DORIS II storage ring at DESY. The ηπ0π0 mass spectrum is dominated by the η’, and the two-photon width Γη’→γγ is determined to be 4.6±0.4±0.6 keV. Limits on ΓX→γγ×BX→ηππ are given for other possible states., Published by Inst., Woodbury, NY
