Abstract：
J/ψ and ψ′ radiative decays to mesons are a good place to look for glueballs, hybrids and for extracting gg-q couplings. Abundant J/ψ and ψ′ events have been collected at the Beijing Electron Positron Collider (BEPC). More data will be collected at upgraded BEPC and CLEO-c. Here we first provide explicit formulae for the angular distribution of photon of the ψ radiative decays in the covariant tensor formalism. Then we discuss helicity formalism of the angular distribution of the ψ radiative decays to two pseudoscalar mesons, and its relation to the covariant tensor formalism.
