TL;DR
This paper calculates the rare top quark decay to a 125 GeV Higgs within a supersymmetric model with local baryon and lepton gauge symmetries, predicting potentially detectable branching ratios.
Contribution
It introduces a calculation of top quark decay in a BLMSSM framework, highlighting the possibility of observing such decays experimentally.
Findings
Branching ratios of t-ch can reach 10^-3
Decay could be detected in near future
Supports the viability of BLMSSM for new physics signals
Abstract
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.
