| Research Abstract |
Lepton flavor violation is studied in the supersymmetric extension of the standard model of particle physics. We compare the lepton sector flavor violation with that of quark sector, and identify the superparticle mass spectrum in which the lepton flavor gives better discovery potential. Related to this, a new mechanism of supersymmetry breaking and mediation is proposed, which can be a low-energy consequence of string theories. It is pointed out that the moduli decay into gravitino pairs has a sizable branching ratio, and its cosmological implications are discussed.
