Tau and muon lepton flavor violations in the littlest Higgs model with T-parity

Understand

Lepton flavor violation in tau and mu processes is studied in the littlest Higgs model with T-parity.

• We consider various asymmetries defined in polarized tau and mu decays.
• Correlations among branching ratios and asymmetries are shown in the following lepton flavor violation processes: mu+ --> e+ gamma, mu+ --> e+ e+ e-, mu- A --> e- A (A = Al, Ti, Au and Pb), tau+ --> mu+ gamma, tau+ --> mu+ mu+ mu-, tau+ --> mu+ e+ e-, tau+ --> mu+ P (P = pi0, eta and eta'), tau+ --> mu+ V (V = rho0, omega and phi), tau+ --> e+ gamma, tau+ --> e+ e+ e-, tau+ --> e+ mu+ mu-, tau+ --> e+ P, tau+ --> e+ V, tau+ --> mu+ mu+ e- and tau+ --> e+ e+ mu-.
• It is shown that large parity asymmetries and time-reversal asymmetries are allowed in mu+ --> e+ e+ e-.
