| 英文摘要 | We perform a helicity amplitude analysis for the processes of e(+)e(-) -> j/psi, psi(2s) -> xi(1530) (xi) over bar (1530) -> pi pi xi(xi) over bar -> 4 pi lambda(lambda) over bar -> 6 pi p (p) over bar. the joint angular distribution for these processes are obtained, which allows a proper estimation of the detection efficiency using helicity amplitude information. in addition, the sensitivities of measurement of hyperon asymmetry decay parameters for these processes are discussed.
