Abstract

With accumulation of high statistics data at BES and CLEO-c, many new interesting channels can get enough statistics for partial wave analysis (PWA). Among them, $ψ \to γ p p ˉ, γ Λ Λ ˉ, γ Σ Σ ˉ, γ Ξ Ξ ˉ$ channels provide a good place for studying baryon-antibaryon interactions; the double radiative decays $ψ \to γ γ V$ with $V \equiv ρ, ω, ϕ$ 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 $ψ \to γ R \to γ γ V$ ; $ψ (2 S) \to γ χ_{c 0, 1, 2}$ with $χ_{c 0, 1, 2} \to K K ˉ π^{+} π^{-}$ and $2 π^{+} 2 π^{-}$ decays are good processes to study $χ_{c J}$ charmonium decays. Using the covariant tensor formalism, here we provide theoretical PWA formulae for these channels.
