摘要：

Lepton-flavor-violating decays of the type L-->lgammagamma (mu-->egammagamma, tau-->egammagamma, and tau-->mugammagamma) are proposed as new probes of R-parity-violating supersymmetry. Non-penguin diagrams with a sneutrino that decays into two photons via a triangle graph might trigger such decays even in the absence of the corresponding radiative decays into one photon only, e.g. mu-->egamma. Thus, processes of the type L-->lgammagamma may provide an independent probe of new flavor physics.
