Abstract

We discuss the non-decoupling effects on the loop-induced H^± W^∓ Z⁰ vertex in the general two Higgs-doublet model. The decay process H^± → W^± Z⁰ is analyzed at one-loop level and possible enhancement of the decay width is explored. We find that a novel enhancement can be realized by the Higgs non-decoupling effects with large mass difference between charged and CP-odd Higgs bosons. The branching ratio of the process can be a few % ∼ 10%. Therefore the decay mode may be detectable at LHC or future e⁺e^- linear colliders (LC's).
