摘    要:An analysis of the helicity amplitude is performed on the process e^+e^- ψ(2S) → γχcJ→γ∧∧^-→γpπ^-p^-π^+. The joint angular distributions for each decay chain are given, and we focus on discussing the E1 contributions to ψ(2S) radiative decays, and the violation of the helicity selection rule in χcJ decays into hyperon pairs, together with the possibility of observing parity violation in successive hyperon decays.
