Search for Supersymmetry in scenarios with electroweakly produced particles, R-parity violating signatures , or long-lived states

Supersymmetric extensions of the Standard Model provide a broad range of possible phenomenologies that can be probed at collider experiments. In parallel to the searches that target strong production of sparticles with R-parity conserving decay modes, there is increasing interest in signatures that include electroweak production, R-parity violating and long lived SUSY particles. This talk presents a review of the ATLAS results for such searches, focusing on the analyses that make use of $\sqrt{s} = 13$ TeV proton-proton collision data.
