Title: Supersymmetric Higgs mediated lepton flavor violation at a photon collider

Abstract

We study a new signature of lepton flavor violation (LFV) at the photon collider within supersymmetric theories. We consider the minimal supersymmetric standard model within a large tan{beta} scenario with all superpartner masses in the O(TeV) while the heavy Higgs bosons masses lie below the TeV and develop sizable loop induced LFV couplings to the leptons. We consider a photon collider based on an e{sup +}e{sup -} linear collider with {radical}(s)=800 GeV with the parameters of the TESLA proposal and show that, with the expected integrated {gamma}{gamma} luminosity L{sub {gamma}}{sub {gamma}}=200-500 fb{sup -1}, the '{mu}{tau} fusion' mechanism is the dominant channel for the process {gamma}{gamma}{yields}{mu}{tau}bb providing detailed analytical and numerical studies of the signal and backgrounds. We impose on the parameter space present direct and indirect constraints from B physics and rare LFV {tau} decays and find that the LFV signal can be probed for masses of the heavy neutral Higgs bosons A, H from 300 GeV up to the kinematical limit {approx_equal}600 GeV for 30{<=}tan{beta}{<=}60.
