The R-parity Violating MSSM — •Herbert Dreiner1, Benjamin Allanach2, and Athanasios Dedes31Universität Bonn — 2LAPP Annecy — 3IPPP Durham

We embed supersymmetry with broken R-parity into minimal supergravity, with boundary conditions at the GUT scale. We minimize the scalar potantial iteratively and determine the complete low energy (weak scale) particle mass spectrum and couplings as a function of the 5 GUT scale parameters: M0, M1/2, tanβ, A, λ. Where λ is the single R-parity violating coupling we assume. We show how the low-energy neutrino masses depend on λ and thus obtain the strictest bounds to date on all lepton number violating couplings. We furthermore show how a natural scalar tau arises in these models as the LSP. This leads to novel collider signatures which are classified.
