Abstract

The double radiative decays ψ→γγV with V≡ ρ,ω,ϕ have a potential to provide information on the flavor content of any meson resonances (R) with positive charge parity (C=+) and mass above 1 GeV through ψ→γR →γγV. To get the information, one needs both high statistic data and partial wave analysis (PWA). While high statistic data will be available soon at CLEO-c and BES-III, here we provide theoretical PWA formulae for these ψ double radiative decay channels in the covariant tensor formalism.
