Abstract

The doubly charmed baryon was recently observed by LHCb via the decay processes of and . These discovery channels were successfully predicted in a framework in which the short-distance contributions are calculated under the factorization hypothesis and the long-distance contributions are estimated using the rescattering mechanism for the final-state-interaction effects. In this paper, we illustrate the above framework in detail by systematic studies on the two-body baryonic decays involving the doubly charmed baryons , the singly charmed baryons and the light pseudoscalar mesons .
