Two-body charmed baryon nonleptonic weak decays with decuplet baryon involving SU(3) F -breaking effects
Abstract We study the charmed baryon two-body decays of B c → B D M under the SU(3) F flavor symmetry, where B c refers to anti-triplet singly charmed baryons, and B D and M denote decuplet baryons and pseudoscalar mesons, respectively. We consider the released energy dependence of both partial wave...

| description | Abstract We study the charmed baryon two-body decays of B c → B D M under the SU(3) F flavor symmetry, where B c refers to anti-triplet singly charmed baryons, and B D and M denote decuplet baryons and pseudoscalar mesons, respectively. We consider the released energy dependence of both partial waves and phase space for the SU(3) F symmetry breaking effects. With 4 real parameters in total and 8 experimental data points, we achieve a minimal χ 2/d.o.f. value of 0.81, providing a satisfactory explanation to the experiment results. We evaluate the branching ratios and decay asymmetries with unusual positive decay asymmetry in B c → B D M, indicating the nontrivial SU(3) F -breaking effects. The results of the large SU(3) F -breaking effects can be verified in the further research by the experiments at BESIII, Belle II and LHCb. |
