The decay t{yields}bWZ in models with extended Higgs sector

We study the contribution of charged Higgs boson to the rare decay of the quark top t{yields}bWZ in models with extended Higgs sector that include doblets and triplets. Higgs doublets are needed to couple charged Higgs with quarks, whereas the Higgs triplet component is used to obtaing a vertex H{su...

Zusammenfassung:We study the contribution of charged Higgs boson to the rare decay of the quark top t{yields}bWZ in models with extended Higgs sector that include doblets and triplets. Higgs doublets are needed to couple charged Higgs with quarks, whereas the Higgs triplet component is used to obtaing a vertex H{sup +}W{sup -}Z. It is found that this decay mode has a large branching ratio that may allow to test the custodial SU(2){sub c} symmetry.
