英文摘要: We perform an analysis on B-0-(B) over bar (0) mixing in the extension of the minimal supersymmetric standard model where baryon and lepton numbers are local gauge symmetries (BLMSSM) by using the effective Hamiltonian method. And the constraint of a 125 GeV Higgs to the parameter space has also been considered. The numerical results indicate that the contributions of the extra particles can be sizeable in B-0-(B) over bar (0) mixing. For certain parameter sets, the theoretical prediction of mass differences Delta(mB) agrees with the current experimental result. Furthermore, B-0-(B) over bar (0) mixing in the BLMSSM can preliminarily constrain the parameter space. With the development of more precise theoretical analysis and experimental determinations, the B-0-(B) over bar (0) mixing in the BLMSSM will have a clearer picture and the parameter space in this model will also be further constrained.
