双粲重子是最近在LHCb上通过和的衰变过程观测到的。这些发现渠道成功地预测在一个框架中，短距离的贡献计算下的因式分解假设和长距离的贡献估计使用的rescattering机制的最终状态相互作用的影响。本文通过对双粲重子、单粲重子和轻赝标介子的两体重子衰变的系统研究，详细说明了上述框架。
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.
