Abstract：
Recently BESⅡ collaboration observed an enhancement near the pp invariant mass spectrum. Using the covariant tensor formalism, here we provide theoretical formulae for the partial wave analysis (PWA) of the ψ radiative decay channels ψ→γpp, γΛΛ, γ∑∑,γΞΞ. By performing the Monte Carlo simulation, we give the angular distributions for the photon and proton in the process of J/ψ→γ pp, which may serve as a useful reference for the future PWA on these channels.
