DESCRIPTION:The most widely studied supersymmetric scenario is the minimal
  supersymmetric standard model (MSSM).  In this model\, lepton- and baryon
 - number violating interactions are suppressed by a discrete symmetry\, R-
 Parity or Proton Hexality\, to keep the proton stable.  However it is suff
 icient to forbid only lepton- or baryon-number violation.  We thus extend 
 minimal supergravity (mSUGRA) models by adding an R-Parity violating opera
 tor at the unification scale.\n\nThis can change the supersymmetric spectr
 um leading on the one hand to a sneutrino\, smuon or squark as the lightes
 t supersymmetric particle (LSP).  On the other hand\, a wide parameter reg
 ion is reopened\, where the lightest stau is the LSP.  We investigate in d
 etail the conditions leading to non-neutralino LSP scenarios.  We present 
 typical Tevatron and LHC signatures.  Promising signatures are multi-lepto
 n final states\, high-pT muons and jets\, four jet events and like sign mu
 on events.\n
