We consider B{sub 3} minimal supergravity models where we have one lepton number violating L{sub i}Q{sub j}D{sub 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{yields}s{gamma}, and other precision measurements. We furthermore investigate existing restrictions from direct searches at LEP, the Tevatron, and the CERN pp collider. We then give examples for characteristic signatures at the LHC.
