Searches for supersymmetry in resonance production and R-parity violating signatures with the ATLAS detector

An extended QCD sector beyond the minimal supersymmetric standard model or the admission of R-parity violation introduces new signatures where strongly interacting resonances may decay to jets or leptons with no supersymmetric particles escaping the detector. The talk presents results from searches for scalar gluons and R-parity violation in final states with leptons using a data sample recorded in 2011 at sqrt(s)=7 TeV centre-of-mass energy by the ATLAS experiment.
