The quest to discover supersymmetry at the ATLAS experiment

Abstract

The search for supersymmetry with the ATLAS experiment at the CERN Large HadronCollider intensified after the discovery of the Higgs boson in 2012. The search programmeexpanded in both breadth and depth, profiting from the increased integratedluminosity and higher centre-of-mass energy for the collision data collected between2015 and 2018, and gaining new sensitivity to unexplored areas of supersymmetryparameter space through the use of novel experimental signatures and innovativeanalysis techniques. This report summarises the supersymmetry searches at ATLAS usingup to 140 fb−1 of pp collisions at√s = 13 TeV, including the limits set on theproduction of gluinos, squarks, and electroweakinos for scenarios with or without Rparityconservation, and including models where some of the supersymmetric particlesare long-lived.
