Title: Implications of a very light pseudoscalar boson on lepton flavor violation

Abstract

A long-lived very light pseudoscalar boson would favor lepton flavor violating transitions of charged leptons. Its implications on the l{sub i}{yields}l{sub j}{gamma}{gamma} and l{sub i}{yields}l{sub j}e{sup +}e{sup -} transitions are investigated. Assuming that 2m{sub e}<m{sub {phi}}<m{sub {mu}}, it is found that the inequality B(l{sub i}{yields}l{sub j}{gamma}{gamma})<B(l{sub i}{yields}l{sub j}e{sup +}e{sup -}) holds. The experimental constraints on the decays l{sub i}{yields}l{sub j}{gamma}, l{sub i}{yields}l{sub j}l{sub k}l{sub k}, and l{sub i}{yields}l{sub j}{gamma}{gamma} are used to bound the {phi}l{sub i}l{sub j} couplings.

  • Motivated by the observation of neutrino oscillations, we extend the Higgs boson exempt no-scale supersymmetry model by adding three heavy right-handed neutrino chiral supermultiplets to generate the light neutrino masses and mixings. The neutrino Yukawa couplings can induce new lepton-flavor violating couplings among the soft terms in the course of renormalization group running down from the boundary scale. We study the effects this has on the predictions for low-energy probes of lepton-flavor violation (LFV). Heavy right-handed neutrinos also provide a way to generate the baryon asymmetry through leptogenesis. We find that consistency with LFV and leptogenesis puts strong requirements onmore » either the form of the Yukawa mass matrix or the smallness of the Higgs up soft mass. In all cases, we generically expect that new physics LFV is nonzero and can be found in a future experiment.« less
  • Higgs mediated flavor violating electromagnetic interactions, induced at the one-loop level by a nondiagonal Hf{sub i}f{sub j} vertex, with f{sub i} and f{sub j} charged leptons or quarks, are studied within the context of a completely general effective Yukawa sector that comprises SU{sub L}(2)xU{sub Y}(1)-invariant operators of up to dimension-six. Exact formulae for the one-loop {gamma}f{sub i}f{sub j} and {gamma}{gamma}f{sub i}f{sub j} couplings are presented and their related processes used to study the phenomena of Higgs mediated lepton flavor violation. The experimental limit on the {mu}{yields}e{gamma} decay is used to derive a bound on the branching ratio of the {mu}{yields}e{gamma}{gamma}more » transition, which is 6 orders of magnitude stronger than the current experimental limit. Previous results on the {tau}{yields}{mu}{gamma} and {tau}{yields}{mu}{gamma}{gamma} decays are reproduced. The possibility of detecting signals of lepton flavor violation at {gamma}{gamma} colliders is explored through the {gamma}{gamma}{yields}l{sub i}l{sub j} reaction, putting special emphasis on the {tau}{mu} final state. Using the bound imposed on the H{tau}{mu} vertex by the current experimental data on the muon anomalous magnetic moment, it is found that about half a hundred events may be produced in the International Linear Collider.« less
  • We study lepton flavor violation (LFV) associated with tau leptons in the framework of the two Higgs doublet model, in which LFV couplings are introduced as a deviation from Model II Yukawa interaction. Parameters of the model are constrained from experimental results and also from requirements of theoretical consistencies such as vacuum stability and perturbative unitarity. Current data for rare tau decays provide substantial upper limits on the LFV Yukawa couplings in the large tan{beta} region (tan{beta} > or approx. 30), which are comparable with predictions in fundamental theories. Here tan{beta} is the ratio of vacuum expectation values of themore » two Higgs doublets. We show that a search for the LFV decays {phi}{sup 0}{yields}{tau}{sup {+-}}{mu}{sup {+-}} ({tau}{sup {+-}}e{sup {+-}}) of neutral Higgs bosons ({phi}{sup 0}=h,H and A) at future collider experiments can be useful to further constrain the LFV couplings especially in the relatively small tan{beta} region (tan{beta} < or approx. 30), where rare tau decay data cannot give any strong limit.« less
