摘要: Abstract We consider the possibility that Yukawa couplings depend on Higgs field, with motivation of generating fermion mass hierarchy through appropriate powers vacuum expectation value. This leads to drastic modifications branching ratios, new contributions various flavor-violating processes, and observable rates for top quark decay t → h c . The underlying flavor dynamics must necessarily appear at TeV scale is within reach LHC.
