Quark and Lepton Flavour Physics in the Littlest Higgs Model with T-Parity
Abstract
The Littlest Higgs model with T-parity (LHT) contains new sources of flavour and CP violation both in the quark and the lepton sector. They originate from the interactions of ordinary fermions with mirror fermions mediated by new gauge bosons: WH, ZH and AH. The most spectacular departures from the Standard Model are found in KL -> pi0 nu bar nu, K+ -> pi+ nu bar nu, in the CP-asymmetry Spsi phi and in lepton flavour violating decays. In particular, the latter decays offer a clear distinction between the LHT model and the MSSM. We summarize the most interesting results of three extensive analyses of flavour physics in the LHT model.
