Lepton-flavor-violating decays [Formula Presented] as a new probe of supersymmetry with broken R parity

Abstract

Lepton-flavor-violating decays of the type [Formula Presented] [Formula Presented] [Formula Presented] and [Formula Presented] 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. [Formula Presented] Thus, processes of the type [Formula Presented] may provide an independent probe of new flavor physics. © 2003 The American Physical Society.
