We study the hadronic lepton flavor violating tau decays in the littlest Higgs model with T-parity, considering the contributions from T-odd particles and partner fermions, as well as the inclusion of Majorana neutrinos from an inverse seesaw mechanism. Our results show that the mean values are mostly within one order of magnitude below the current upper limits, providing further support for the search of these decays in the quest for new physics.
We first study the hadronic lepton flavor violating tau decays within the littlest Higgs model with T-parity (including one or two pseudoscalars, or a vector resonance). We consider the case where only T-odd particles and partner fermions contribute, and also its extension including Majorana neutrinos coming from an inverse seesaw. In both cases our mean values lie mostly only one order of magnitude below current upper limits, strengthening the case of searching for these decays in the quest for new physics.
