Measurements of $\psi (2S)$ decays into Vector- Tensor final states

Abstract

Decays of the $\psi (2S)$ into vector plus tensor meson final states have been studied with 14 million $\psi (2S)$ events collected with the BESII detector. Branching fractions of $ψ(2S) \rt ωf_{2}(1270)$, $\rho a_2(1320)$, $K^{\ast }(892{)}^0{\bar{K}}_2^{\ast }(1430{)}^0+c.c.$ and $\varphi f_2^{\prime }(1525)$ are determined. They improve upon previous BESI results and confirm the violation of the "12%" rule for $\psi (2S)$ decays to VT channels with higher precision.
