Lepton flavor violation in the Simplest Little Higgs model

Abstract Little HiggsModels are a possible elegant solution to the hierarchy problemon the Higgs mass. As they predict naturally small deviations with respect to SM results, they are in agreement with all current experimental data. In this contribution, we review lepton flavorviolation in the Simplest Little Higgsmodel focusing on semileptonic lepton flavorviolating tau decays (where some new results are presented) and H → l l ′ . Within this model, the most promising decay channels for discovering lepton flavorviolation are μ → e conversion in nuclei, μ → e γ ( ⁎ ) , τ → ( e / μ ) γ and τ → ( e / μ ) ( π + π − / ρ ) .
