英文摘要: A quark pair creation model is introduced to study the chi(cJ) exclusive decays into baryon-antibaryon pairs. The decay widths for processes chi(cJ) --> B (B) over bar (J = 0, 2; B = A, Sigma(0), Xi(-)) are evaluated phenomenologically with an explicit' inclusion of the properties for outgoing baryons described by wave functions in the naive quark model. The results show that states chi(cJ) (J = 0, 2) decay into A (A) over bar pair with a larger branching ratio than into pp pair.
