报告题目:Two-body doubly charmful baryonic B decays
摘 要:In this talk, I would like to present our recent study of the two-body doubly charmful baryonic B decays with SU(3) flavor symmetry. It is found that the W-exchange contribution, previously neglected in studies, needs to be taken into account, such that the significant discrepancy between the theoretical estimation and experimental data for B(B^0\to\Lambda_c^+\bar\Lambda_c^-) can be alleviated. Consequently, it leads to non-zero branching fractions for the pure W-exchange decay channels, of which the theoretical predictions will also be given.
