| 英文摘要 | Abundant psi' events have been collected at the beijing electron positron collider-ii (bepc ii) that could undoubtedly provide us with a great opportunity to study the more attractive charrnonium decays. as has been noticed before, in the process of j/psi, decaying to the baryonic final states, pk-(lambda) over bar, the evident a* and n* bands have been observed. similarly, by using the product of chi cj from psi' radiative decay, we may confirm this or find some extra new resonances. chi c0's data samples will be more than xc1,2, taking into account the larger branching ratio of psi' -> gamma chi c0. here, we provide explicit partial wave analysis formulae for the very interesting channel psi' -> gamma chi c0 -> gamma pk(-)(lambda) over bar. |
