The analysis is performed using 139 fb(-1) of proton-proton collision data taken at a centre-of-mass energy root s = 13 delivered by the Large Hadron Collider and recorded by the ATLAS experiment. No statistically significant excess of events above the Standard Model expectation is found. Limits are set on the direct production of squarks and gluinos in simplified models. Masses of gluino (squark) up to 2.2 (1.4 ) are excluded at 95% confidence level for a light (chi) over tilde (0)(1).eninfo:eu-repo/semantics/openAccessSupersymmetryExtensionDecayWeakArticle2-s2.0-8511171527810.1140/epjc/s10052-021-09344-w7Q181Q2WOS:000691564500001
