Sumario:Even though the experimental evidence is absent, weak-scale supersymmetry (SUSY) remains one of the best motivated and studied Standard Model extensions to date. There are many ways that searches for weak-scale supersymmetry interact with QCD: QCD scaling rules are used in background estimation techniques; jet sub-structure is exploited for separating signal and background; signal cross-sections rely on higher-order calculations and resummation, etc. For the search for R-hadrons, hadrons including long-lived SUSY particles, additional complex QCD issues arise. This proceeding summarizes recent ATLAS results on supersymmetry searches, with a focus on those aspects that most strongly interact with QCD.
