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…
Features of Motion Around Charged D-Stars
Xiang-hua Zhai, Li-ping Fu
The motion of light and a neutral test particle around the charged D-star has been studied. The difference of the deficit angle of light from the case in asymptotically flat spacet…
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…
Observation of a near-threshold enhancement in th p pbar mass spectrum from radiative J/psi-->gamma p pbar decays
BES Collaboration, J. Z. Bai, Y. Ban +1
We observe a narrow enhancement near 2mp in the invariant mass spectrum of ppbar pairs from radiative J/psi-->gamma ppbar decays. The enhancement can be fit with either an S- or P-…
