英文摘要	An analysis of the helicity amplitude is performed on the process e(+)e(-) -> psi(2S) -> gamma chi(cJ) -> gamma Lambda(Lambda) over bar -> gamma p pi(-)(p) over bar pi(+). The joint angular distributions for each decay chain are given, and we focus on discussing the E1 contributions to psi(2S) radiative decays, and the violation of the helicity selection rule in chi(cJ) decays into hyperon pairs, together with the possibility of observing parity violation in successive hyperon decays.
