Searches for R-Parity violating SUSY with lepton number violation

The violation of R-parity allows new signatures to be pursued in the search for supersymmetry at the LHC. This talk presents the latest results from the ATLAS experiment using 20/fb of pp LHC collision data of searches for R-parity violating SUSY scenarios with lepton number violation. The results presented are for dedicated searches for resonances, as well as a systematic analysis of the constraints placed on R-parity violating models with lepton flavour violation by the Run-1 ATLAS searches, including those which were originally developed to target R-parity conserving models.
