摘要A simple quark pair creation model is introduced to study exclusive decays of X-cJ into baryon-antibaryon pairs. With this simple model, some exclusive decay processes, for example, x(c0) --> B (B) over bar (B = A, Sigma(0), Xi(-)) are investigated and their decay widths are evaluated by inclusion of the properties of outgoing baryons, and the results show that the strengthened decay channels x(cJ) Lambda(&ULambda;) over bar (J = 0, 2) are easily understood by considering only the color singlet contribution of P-wave charmonium.
