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

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.

Abstract

We present a study of inclusive p0 and ? production ine+e- annihilation at ". Our analysis is based on integrated luminosities of 46.2 pb-1 taken at the ? (1 S) resonance and 42.1 pb-1 taken in the neighboring continuum. We measure the inclusive p0 and ? spectra for direct ?

Abstract

The Crystal Ball detector at thee+e− storage ring DORIS II has been used to analyze exclusive semileptonic decays ofB mesons produced at γ(4S) energies. The decayB→evD* has been observed with a branching ratio of (7.0±1.8±1.4)% using theπ°D decay mode of theD*. In addition we have searched for the exclusive semileptonic decayB±→e±vπ0. 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.
