Polarization study of the P-wave charmonium radiative decay into a light vector meson at $e^{+}{e}^{-}$ collider experiment

Yong-Qing Chen, Peng-Cheng Hong, Zhuo Chen +2

In this work, a formalism is presented for the helicity amplitude analysis of the decays $\psi (2S)\to {\gamma }_1{\chi }_{cJ},{\chi }_{cJ}\to {\gamma }_{2}V(V={\rho }^0,\varphi ,\omega )$~(the subscript 1,2 is used to disti…
