An effective lagrangian description of charged Higgs decays H+ -> Wg, WZ and Wh

الأصل · EN

Charged Higgs decays are discussed within an effective lagrangian extension of the two-higgs doublet model, assuming new physics appearing in the Higgs sector of this model. Low energy constrains are used to imposse bounds on certain dimension -six operators that describe the modified charged Higgs interactions. These bounds are used then to study the decays H+ -> Wg, WZ and Wh, which can have branching ratios of order 10-5, 10-1 and O(1), respectively; thse modes are thus sensitive probes of the symmetries of the Higgs sector that could be tested at future colliders.
