| dc.description | Recently BES2 collaboration observed an enhancement near the $p\bar p$ 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 $ψ\to γp\bar p, γΛ\bar Λ, γΣ\barΣ, γΞ\bar Ξ$ . By performing the Monte Carlo simulation, we give the angular distributions for the photon and proton in the process of $J/ψ\to γp\bar p$, which may serve as a useful reference for the future PWA on these channels. | |
