Search for the C-parity violating process J/psi->gamma gamma via psi(2S)->pi+pi- J/psi

M. Ablikim, J. Z. Bai

Using 14.0\times 10^6 ψ(2S) events collected with the BES-II detector, the C-parity violating process J/psi->gamma gamma via psi(2S)->pi+pi- J/psi is studied. We determine a new up…

Precison Measurements of the Mass, the Widths of $ψ (3770)$ Resonance and the Cross Section $σ [e^{+} e^{-} \to ψ (3770)]$ at $E_{cm} = 3.7724$ GeV

M. Ablikim et al.

By analyzing the $R$ values measured at 68 energy points in the energy region between 3.650 and 3.872 GeV reported in our previous paper, we have precisely measured the mass, the t…

Measurement of $\psip$ Radiative Decays

M. Ablikim, J. Z. Bai, Y. Ban +1

Using 14 million psi(2S) events accumulated at the BESII detector, we report first measurements of branching fractions or upper limits for psi(2S) decays into gamma ppbar, gamma 2(…

Evidence of $κ$ particle in $J / ψ \to K ˉ^{*} (892)^{0} K^{+} π^{-}$

J. Z. Bai, H. Q. Zheng, T. N. Ruan

Based on a $J / ψ$ data sample of $7.8 \times 1 0^{6}$ events at BESI, the decay of $J / ψ \to K ˉ^{*} (892)^{0} K^{+} π^{-}$ is studied and a low mass enhancement, which is believed not comin…
