We present the results of an extensive analysis of flavour physics in both quark and lepton sectors, in the Littlest Higgs model with T-parity (LHT). In the quark sector, we identify some interesting scenarios for new mirror quark masses and V_Hd mixing matrix that satisfy the existing experimental constraints from K and B physics and simultaneously allow large New Physics effects in rare decays and CP-violating observables. In the lepton sector, where flavour violation in the Standard Model is highly suppressed by small neutrino masses, LHT effects turn out to be naturally huge and could be seen in the near future measurements of lepton flavour violating decays.

Abstract
We present the results of an extensive analysis of flavour physics in both quark and lepton sectors, in the Littlest Higgs model with T-parity (LHT). In the quark sector, we identify some interesting scenarios for new mirror quark masses and V_Hd mixing matrix that satisfy the existing experimental constraints from K and B physics and simultaneously allow large New Physics effects in rare decays and CP-violating observables. In the lepton sector, where flavour violation in the Standard Model is highly suppressed by small neutrino masses, LHT effects turn out to be naturally huge and could be seen in the near future measurements of lepton flavour violating decays.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
