| 摘 要： | In this paper, we calculate the top quark rare decays t →cγ and v in an extension of the standard model, where baryon number and lepton number are local gauge symmetries. Adopting reasonable assumptions on the parameter space, we find that the branching ratios of t →cγ and t →cg can reach 10^-6 and 10^-5 respectively, which can be detected in near future.

| Abstract: | In this paper, we calculate the top quark rare decays t→cγ and t→cg in an extension of the standard model, where baryon number and lepton number are local gauge symmetries. Adopting reasonable assumptions on the parameter space, we find that the branching ratios of t→cγ and t→cg can reach 10-6 and 10-5 respectively, which can be detected in near future. |
