Phenomenology of lepton flavor violation in two Higgs doublet model type III from (g-2)μ and leptonic decays -: art. no. 075011

We constrain some lepton flavor violating vertices in the context of the two Higgs doublet model type III, assuming that the lightest Higgs scalar mass m(h)(0) is about 115 GeV. Specifically, based on the g-2 muon factor and the decay width of mu-->egamma, the following quite general bounds are obtained: 7.62x10(-4)less than or similar toxi(mutau)(2)less than or similar to4.44x10(-2); xi(etau)(2)less than or similar to2.77x10(-14). Additionally, based on the processes tau-->mugamma, and tau-->mumumu, bounds on xi(tautau) and xi(mumu) are also obtained; such constraints on these parameters still give enough room for either a strong suppression or strong enhancement on the coupling of any Higgs boson to a pair of tau leptons or a pair of muons. Furthermore, upper limits on the decay widths of the leptonic decays tau-->egamma and tau-->eee are calculated, finding them to stay far from the reach of near future experiments.
