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.

Lepton flavor violating signals of the littlest Higgs model with T parity via e{sup +}e{sup -} and {gamma}{gamma} collisions at the ILC

Journal Article Wei, Ma ; Chongxing, Yue ; Jiao, Zhang ; ... - Physical Review. D, Particles Fields

Taking into account the constraints on the free parameters of the littlest Higgs model with T parity (called the LHT model) from some rare decay processes, such as {mu}{yields}e{gamma} and {mu}{yields}3e, we consider the contributions of the LHT model to the lepton flavor violating (LFV) processes e{sup +}e{sup -}{yields}l{sub i}l{sub j} and {gamma}{gamma}{yields}l{sub i}l{sub j} (i{ne}j). We find that the LHT model can indeed produce significant contributions to these LFV processes and its LFV signal might have a chance of being observed in the future International Linear Collider experiments.

Enhanced lepton flavor violation with massless neutrinos; A study of muon and tau decays

Journal Article Gonzalez-Garcia, M C ; Valle, J W.F. - Modern Physics Letters A; (United States)

This paper reports on lepton flavor violating rates that can be experimentally measurable even if the observed neutrinos are strictly massless. We make a study of the attainable rates for anomalous leptonic muon and tau number violating decays such as {mu} {yields} e{gamma}, {mu} {yields} 3e, {tau} {yields} {mu}{gamma}, {tau} {yields} e{gamma}, {tau} {yields} {mu}{mu}{sup +}{mu}{sup {minus}}, {tau} {yields} ee{sup +}e{sup {minus}}, {tau} {yields} e{mu}{sup +}{mu}{sup {minus}}, etc. as well as semileptonic lepton flavor violating tau decays such as {tau} {yields} {mu}{pi}{sup 0}, {tau} {yields} e{eta}, etc. All muonic violating decays can be as large as the present limits frommore »« less

Lepton flavor violating {tau} decays in the type-III seesaw mechanism

Journal Article Arhrib, Abdesslam ; Benbrik, Rachid ; Chen, C -H ; ... - Physical Review. D, Particles Fields

In this paper, the lepton flavor violating {tau}{yields}lP(V) (P, V={pi}{sup 0}, {eta}, {eta}{sup '}, {rho}{sup 0}, {omega}, {phi}) and {tau}{yields}3l (l=e, {mu}) decays are studied in the framework of the type-III seesaw model, in which new triplet fermions with a zero hypercharge (Y=0) interact with ordinary lepton doublets via Yukawa couplings, and affect tree-level leptonic Z-boson couplings. We investigate the experimental bound from the leptonic Z decay to get constraints on the existing parameters space. We predict that the upper limits on the branching ratios of {tau}{yields}lP(V) and {tau}{yields}3l can reach the experimental current limits.

Lepton flavor violating semileptonic {tau} decays {tau}{yields}lP(V) in a topcolor scenario

Journal Article Chongxing, Yue ; Lihong, Wang ; Wei, Ma - Physical Review. D, Particles Fields

The contributions of the neutral top-pion {pi}{sub t}{sup 0} and the nonuniversal gauge boson Z{sup '} predicted by the topcolor scenario to the lepton flavor violating semileptonic {tau} decays {tau}{yields}lP(V) (P={pi}{sup 0}, {eta}, {eta}{sup '} and V={rho}{sup 0}, {phi}) are discussed. We find that the contributions of Z{sup '} to these decay processes are generally larger than those from {pi}{sub t}{sup 0}. {pi}{sub t}{sup 0} can only make the value of the branching ratio Br({tau}{yields}lP) in the range of 1x10{sup -11}-1x10{sup -16}, which is far below the sensitivity of foreseeable experiments. With reasonable values of the free parameters, the nonuniversalmore »« less

Lepton flavor violation in the little Higgs model with T parity

Journal Article Choudhury, S Rai ; Cornell, A S ; Deandrea, A ; ... - Physical Review. D, Particles Fields

Little Higgs models with T-parity may provide us with a new source of lepton flavor violation, as such, in this paper we consider the anomalous magnetic moment of the muon (g-2){sub {mu}} and the lepton flavor violating decays {mu}{yields}e{gamma} and {tau}{yields}{mu}{gamma} in the little Higgs model with T-parity [A. Goyal, hep-ph/0609095.]. Our results show that the present experimental constraints of {mu}{yields}e{gamma} are a much more useful tool for constraining the new sources of flavor violation, than from the other processes considered here, which are present in T-parity models.
