Lepton flavor violation in the little Higgs model with T parity

Abstract

Little Higgs models with T-parity may provide us with a new source of lepton flavor violation, as such, in this paper we consider the anomalous magnetic moment of the muon (g-2)_μ and the lepton flavor violating decays μ→eγ and τ→μγ in the little Higgs model with T-parity [A. Goyal, hep-ph/0609095.]. Our results show that the present experimental constraints of μ→eγ are a much more useful tool for constraining the new sources of flavor violation, than from the other processes considered here, which are present in T-parity models.
