Searches for supersymmetry in resonance production, R-parity violating signatures and events with long-lived particles at LHC

An extended QCD sector beyond the minimal supersymmetric standard model or the admission of R-parity violation introduces new signatures to the search for supersymmetry at the LHC. Strongly interacting resonances may decay to jets, sleptons via lepton-flavour violating processes and lightest supersymmetric particles may decay into many leptons with or without missing trans- verse momentum. Several supersymmetric models also predict massive long-lived supersymmet- ric particles. Such particles may be detected through abnormal specific energy loss, appearing or disappearing tracks, displaced vertices, long time-of-flight or late calorimetric energy deposits. These proceedings present recent results from searches for supersymmetry in resonance production, R-parity violating signatures and events with long-lived particles with the ATLAS and CMS detectors.
