Resonances in $J / ψ \to ϕ π^{+} π^{-}$ and $ϕ K^{+} K^{-}$

M. Ablikim

A partial wave analysis is presented of $J / ψ \to ϕ π^{+} π^{-}$ and $ϕ K^{+} K^{-}$ from a sample of 58M $J / ψ$ events in the BES II detector. The $f_{0} (980)$ is observed clearly in both sets of…

Measurement of the final states $ω π^{0}$ , $ρ η$ , and $ρ η^{^{'}}$ from $\psip$ electromagnetic decays and $\ee$ annihilations

M. Ablikim

Cross sections and form factors for $\ee \to \wpi$, $ρ η$ , and $ρ\etap$ at center of mass energies of 3.650, 3.686, and 3.773 GeV are measured using data samples collected with the…

Search for K_S K_L in psi'' decays

M. Ablikim

K_S K_L from psi'' decays is searched for using the psi'' data collected by BESII at BEPC, the upper limit of the branching fraction is determined to be B(psi''--> K_S K_L) < 2.1\t…

Determination of BR(chi_{cJ} --> p \bar{p}) in psi(2S) decays

J. Z. Bai, BES Collaboration

The processes psi(2S) --> gamma chi_{cJ}, chi_{cJ} --> p pbar (J=0,1,2) are studied using a sample of 14X10^6 psi(2S) decays collected with the Beijing Spectrometer at the Beijing…
