A Study of J/psi-->gamma gamma V(rho,phi) Decays with the BESII Detector
BES Collaboration
Using a sample of events collected with the BESII detector, radiative decays , where or , are studied. A resonance around 1420 MeV/c (…
ψ(2S) Decays into $\J$ plus Two Photons
BES collaboration
Using $γγJ/ψ, J/ψ\ra e^+ e^-$ and events from a sample of $\psip$ decays collected with the BESII detector, the branching fractions for $\psip\ra π^0\J$…
Improved measurement of the branching ratio of J/psi-->K_S K_L
J. Z. Bai
The branching ratio of J/psi-->K_S K_L is measured with improved precision to be B(J/psi-->K_S K_L) = (1.82\pm 0.04\pm 0.13)\times 10^{-4}. using J/psi data collected with the Beij…
Evidence of psi(3770) non-DD-bar Decay to J/psi pi+pi-
BES Collaboration
Evidence of decays to a non- final state is observed. A total of $ψ(3770) \to \PPJP$ events are obtained from a data sample of 27.7 $\r…
A Measurement of the Mass and Full-Width of the Meson
J. Z. Bai
In a sample of 7.8 million decays collected in the Beijing Spectrometer, the process J/ is observed for five different decay channels: , $π^+π^-…
Measurement of the Total Cross Section for Hadronic Production by e+e- Annihilation at Energies between 2.6-5 Gev
J. Z. Bai
Using the upgraded Beijing Spectrometer (BESII), we have measured the total cross section for annihilation into hadronic final states at center-of-mass energies of 2.6, 3.…
Study of the Hadronic Decays of χ_c States
J. Z. Bai
Hadronic decays of the P-wave spin-triplet charmonium states χ_cJ (J=0,1,2) are studied using a sample of ψ(2S) decays collected by the BES detector operating at the BEPC storage r…
Determination of the J/psi Leptonic Branching Fraction via psi(2S) -> pi^+ pi^- J/psi
J. Z. Bai
A comparison of the rates for psi(2S) -> pi^+ pi^- J/psi, J/psi -> l^+l^- and J/psi -> anything is used to determine the J/psi leptonic branching fractions. The results are B(J/psi…
