摘要：

We study the loop-induced flavor-changing decay tc+ in a nonlinear R gauge for the standard model with three and four generations and in models with two Higgs doublets. We find that this decay could be relevant only in a scenario with two Higgs doublets and the mass of the fourth-generation b quark larger than mt. Under these conditions, the flavor-changing electromagnetic decays Tq*Dq(TqDq*) may surpass the standard electromagnetic transition Tq*Tq. © 1990 The American Physical Society.
