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…
