Supersymmetric Higgs mediated lepton flavor violation at a photon collider

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 tanβ 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+e- linear collider with √(s)=800 GeV with the parameters of the TESLA proposal and show that, with the expected integrated γγ luminosity Lγγ=200-500 fb-1, the 'μτ fusion' mechanism is the dominant channel for the process γγ→μτbb 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 τ 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 ≅600 GeV for 30≤tanβ≤60.
