Abstract

We consider $B_{3}$ minimal supergravity models where we have one lepton number violating $L_{i} Q_{j} {\bar{D}}_{k}$ operator at the grand unification scale. This can alter the supersymmetric mass spectrum leading to a sneutrino as the lightest supersymmetric particle in a large region of parameter space. We take into account the restrictions from neutrino masses, the muon anomalous magnetic moment, $b \to s γ$ , and other precision measurements. We furthermore investigate existing restrictions from direct searches at LEP, the Tevatron, and the CERN $p \bar{p}$ collider. We then give examples for characteristic signatures at the LHC.
