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…

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…

First Measurement of the Branching Ratio of $J / ψ \to γ f_{2} (1270) f_{2} (1270)$

BES Collaboration, M. Ablikim

Using 58 million $J / ψ$ events taken with the BES II detector at the Beijing Electron Positron Collider, a new decay mode $J / ψ \to γ f_{2} (1270) f_{2} (1270) \to γ π^{+} π^{-} π^{+} π^{-}$ is obser…
