Constraints on promptly decaying supersymmetric particles with lepton-number- and R-parity-violating interactions using Run-1 ATLAS data

Sumario:In this document, a selection of ATLAS searches for supersymmetry (SUSY), mostly optimised for R-parity-conserving SUSY, are reinterpreted in new R-parity-violating SUSY models where an unstable neutralino decays promptly to leptons and/or jets. All forms of renormalisable R-parity-violating interactions with lepton-number violation are considered. The production of squarks and gluinos is constrained for different neutralino masses and decay modes. In most cases lower limits on the squark and gluino masses of $m\gtrsim 1$ TeV are obtained; exceptions to this rule are located and discussed. Additionally, bilinear R-parity violation is considered in a model with a natural SUSY spectrum with light third-generation squarks and higgsinos. Only a small portion of the explored parameter space remains unexcluded, where $m_{\tilde{q}_{L,3}} > 810$ GeV.
