摘要

The decay t → cV(V = y,Z,g)processes in mirror twin Higgs models with colorless top partners are studied in this paper.We report that the branching ratios of these decays can strongly affect the standard model ex-pectations in some parameter spaces and may be detectable according to the current precision electroweak measure-ments.Thus,constraints on the model parameters may be obtained from the branching fraction of the decay pro-cesses,which may serve as a robust detection tool for this new physics model.
