Mass spectrum in R-parity violating minimal supergravity and benchmark points

We investigate in detail the low-energy spectrum of the R-parity violating minimal supergravity model using the computer program softsusy. We impose the experimental constraints from the measurement of the anomalous magnetic moment of the muon, (g-2)μ, the decay b→sγ as well as the mass bounds from direct searches at colliders, in particular on the Higgs boson and the lightest chargino. We also include a new calculation for the R-parity violating contribution to Br(Bs→μ+μ-). We then focus on cases where the lightest neutralino is not the lightest supersymmetric particle (LSP). In this region of parameter space either the lightest scalar tau (stau) or the scalar tau neutrino (tau sneutrino) is the LSP. We suggest four benchmark points with typical spectra and novel collider signatures for detailed phenomenological analysis and simulation by the LHC collaborations
