Covariant tensor formalism for partial wave analyses of $\psi$ decays into $\gamma B\bar B$, $\gamma\gamma V$ and $\psi(2S)\to\gamma\chi_{c0,1,2}$ with $\chi_{c0,1,2}\to K\bar K \pi^+\pi^- $ and $2\pi^+2\pi^-$

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, $\psi \to \gamma p\bar p, \gamma\Lambda\bar \Lambda, \gamma\Sigma \bar\Sigma, \gamma\Xi\bar \Xi$ 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 ® with positive charge parity ( $C = +$ ) and mass above 1 GeV through $\psi\to\gamma R \to\gamma\gamma V $;$ \psi(2S)\to\gamma\chi_{c0,1,2} $w i t h$ \chi_{c0,1,2}\to K\bar K \pi^+\pi^- $a n d$ 2\pi^+2\pi^- $d e c a y s a r e g o o d p r o c e s s e s t o s t u d y$ \chi_{cJ}$ charmonium decays. Using the covariant tensor formalism, here we provide theoretical PWA formulae for these channels.
