Measurements of $ψ(2S)$ decays into Vector- Tensor final states
Abstract
Description
Decays of the $ψ(2S)$ into vector plus tensor meson final states have been studied with 14 million $ψ(2S)$ events collected with the BESII detector. Branching fractions of $ψ(2S) \rt ωf_{2}(1270)$, $ρa_2(1320)$, $K^*(892)^0\bar{K}^*_2(1430)^0+c.c.$ and $ϕf_2^{\prime}(1525)$ are determined. They improve upon previous BESI results and confirm the violation of the "12%" rule for $ψ(2S)$ decays to VT channels with higher precision.
