Abstract (data abstract)
A search for supersymmetric partners of gluons and quarks is presented, involving signatures with jets and either two isolated leptons ($e$ or $\mu$) with the same electric charge, or at least three isolated leptons. The analysis also relies on $b$-tagged jets or missing transverse momentum to extend its sensitivity. A data sample of proton--proton collisions at $\sqrt{s}$ = 13 TeV recorded with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to a total integrated luminosity of 139 fb$^{-1}$, is used for the search. No significant excess over the Standard Model expectation is observed. The results are interpreted in simplified supersymmetric models featuring both $R$-parity conservation and $R$-parity violation, extending the exclusion limits from previous searches up to 1600 GeV for gluino masses and 750 GeV bottom and top squark masses in these scenarios.
