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…

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…

Measurements of $ψ (2 S)$ decays into $ϕ π^{0}$ , $ϕ η$ , $ϕ η^{^{'}}$ , $ω η$ , and $ω η^{^{'}}$

BES Collaboration

Decays of the $ψ (2 S)$ into Vector plus Pseudoscalar meson final states have been studied with 14 million $ψ (2 S)$ events collected with the BESII detector. Branching fractions of $ψ…

Observation of the decay $\psip\rar\kstark$

BES Collaboration, M. Ablikim

Using 14 million $ψ (2 S)$ events collected with the BESII detector, branching fractions of $\psip\rar\kstarkpm$ and $\kstarknn$ are determined to be: $\calB(\psip\rar\kstarkpm)=(2.9…
