Constraints from LFV processes in the Higgs triplet model

Abstract

Constraints from lepton flavor violating processes are translated into lower bounds on in the Higgs Triplet Model by considering correlations through the neutrino mass matrix. It is shown that μ → eγ, rare τ decays (especially, ), and the muonium conversion can give a more stringent bound on in some parameter regions than the bound from which is expected naively to give the most stringent one. We consider the cases of suppressed not only for CP-conserving sets of phases but also for arbitrary values.
