Abstract

We discuss the phenomenology of doubly and singly charged Higgs bosons [of SU(2)L-triplet fields] in the simplest A4-symmetric version of the Higgs triplet model. Mass eigenstates of these Higgs bosons are obtained explicitly from the Higgs potential. It is shown that their decays into a pair of leptons have unique flavor structures which can be tested at the LHC if some of their masses are below the TeV scale. Sizable decay rates for τ→μ̄ee and τ→ēμμ can be obtained naturally, while other τ→̄′′′, μ→ēee, and →γ, are almost forbidden in this model. Contributions of these Higgs bosons to the nonstandard interactions of neutrinos are also considered.
