英文摘要	The helicity amplitudes for the processes of e(+)e(-) -> J/psi -> gamma eta(c) -> gamma Y (Y) over bar (Y : hyperon) are presented, together with the joint angular distributions for eta(c) decays into Lambda(Lambda) over bar, Sigma(0)(Sigma) over bar (0), Xi(-)(Xi) over bar (+), and The sensitivities to measure the hyperon decay parameters in these decays are evaluated based on the helicity amplitudes. The prospects to test the Bell inequality in experiment using the decay of eta(c) -> Lambda(Lambda) over bar are discussed.
