文摘A quark pair creation model is introduced to study the XeJ exclusive decays into baryon-antibarvon pairs.The decay widths for processes Xcj→B(B^-) (J=0, 2;B=∧,∑^0,Ξ^-) 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 XcJ (J =0.2) decay into ∧(∧^-) pair with a larger branching ratio than into p(p^-) pair.
