Vector Leptons in the Higgs Triplet Model

Abstract

We analyze the phenomenological implications of introducing vector-like leptons on the Higgs sector in the Higgs Triplet Model. We impose only a parity symmetry which disallows mixing between the new states and the ordinary leptons. If the vector leptons are allowed to be relatively light, they enhance or suppress the decay rates of loop-dominated neutral Higgs bosons decays h -> gamma gamma and h -> Z gamma, and affect their correlation. An important consequence is that, for light vector leptons, the decay patterns of the the doubly-charged Higgs boson will be altered, modifying the restrictions on their masses.
