Top quark decay to a 125GeV Higgs in BLMSSM
  In this paper, we calculate the top quark rare decay t-ch in a supersymmetric extension of the standard model where baryon and lepton numbers are local gauge symmetries. Adopting reasonable assumptions on the parameter space, we find that the branching ratios of t-ch can reach 10^-3, which can be detected in near future.
