Lepton Flavor Violation in the LHT - A Clear Distinction from Supersymmetry

Abstract

The Littlest Higgs Model with T-Parity (LHT) contains new sources of flavor and CP violation both in the quark and lepton sector. These have their origin in interactions of ordinary fermions with mirror fermions mediated by new heavy gauge bosons. Large deviations from the Standard Model (SM) are to be expected in the lepton sector where tiny neutrino masses suppress the SM predictions by many orders of magnitude below the experimentally accessible level. Here we give a brief summary of LFV processes relevant for the foreseeable future and point out that correlations between branching ratios of LFV decays in the LHT exhibit a structure vastly different from their analogues in the MSSM, thus allowing for a transparent distinction between these two models.
