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

Abstract

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}{sup +}{yields}e{sup +}{gamma}, {mu}{sup +}{yields}e{sup +}e{sup +}e{sup -}, {mu}{sup -}A{yields}e{sup -}A (A=Al, Ti, Au, and Pb), {tau}{sup +}{yields}{mu}{sup +}{gamma}, {tau}{sup +}{yields}{mu}{sup +}{mu}{sup +}{mu}{sup -}, {tau}{sup +}{yields}{mu}{sup +}e{sup +}e{sup -}, {tau}{sup +}{yields}{mu}{sup +}P (P={pi}{sup 0}, {eta} and {eta}{sup '}), {tau}{sup +}{yields}{mu}{sup +}V (V={rho}{sup 0}, {omega} and {phi}), {tau}{sup +}{yields}e{sup +}{gamma}, {tau}{sup +}{yields}e{sup +}e{sup +}e{sup -}, {tau}{sup +}{yields}e{sup +}{mu}{sup +}{mu}{sup -}, {tau}{sup +}{yields}e{sup +}P, {tau}{sup +}{yields}e{sup +}V, {tau}{sup +}{yields}{mu}{sup +}{mu}{sup +}e{sup -} and {tau}{sup +}{yields}e{sup +}e{sup +}{mu}{sup -}. It is shown that large parity asymmetries and time-reversal asymmetries are allowed in {mu}{sup +}{yields}e{sup +}e{sup +}e{sup -}. For {tau} lepton flavor violation processes, sizable asymmetries are possible reflecting characteristic chirality structure of lepton flavor violating interactions in this model.
