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…
A Measurement of Psi(2S) Resonance Parameters
BES Collaboration, J. Z. Bai
Cross sections for e+e- to hadons, pi+pi- J/Psi, and mu+mu- have been measured in the vicinity of the Psi(2S) resonance using the BESII detector operated at the BEPC. The Psi(2S) t…
First Measurement of the Branching Fraction of the Decay psi(2S) --> tau tau
J. Z. Bai
The branching fraction of the psi(2S) decay into tau pair has been measured for the first time using the BES detector at the Beijing Electron-Positron Collider. The result is $B_{τ…
