The quest to discover supersymmetry at the ATLAS experiment

Abstract

The search for supersymmetry with the ATLAS experiment at the CERN Large Hadron Collider intensified after the discovery of the Higgs boson in 2012. The search programme expanded in both breadth and depth, profiting from the increased integrated luminosity and higher centre-of-mass energy of Run 2, and gaining new sensitivity to unexplored areas of supersymmetry parameter space through the use of new experimental signatures and innovative analysis techniques. This report summarises the supersymmetry searches at ATLAS using up to 140 fb${}^{-1}$ of $pp$ collisions at $\sqrt{s}=13$ TeV, including the limits set on the production of gluinos, squarks, and electroweakinos for scenarios either with or without R-parity conservation, and including models where some of the supersymmetric particles are long-lived.
