摘要
We study lepton flavor violation (LFV) within the Littlest Higgs Model with T parity (LHT) realizing an inverse seesaw (ISS) mechanism of type I. With respect to the traditional LHT, there appear new O(10 TeV) Majorana neutrinos, driving LFV. For tau -> ll'(l) over bar '' (including wrong-sign, l = e, mu) decays and mu -> e conversion in Ti, we get typical rates only one order of magnitude below present bounds (l -> l'gamma can reach the current upper limit) and for Z -> (tau) over barl, mu -> ee (e) over bar and conversion in Au, results are within two orders of magnitude from present limits. Correlations among modes are drastically different to the traditional LHT and other models, which would ease the confrontation of this scenario to eventual measurements of LFV processes involving charged leptons.
