or μ
) with the same electric charge or at least three isolated leptons is presented in this proceeding. To extend its sensitivity, the search uses jets originating from b
-quarks, missing transverse momentum, and other observables. The analysis uses 13.2 fb−1
of proton-proton collision data at √s
= 13 TeV recorded with the ATLAS detector at the LHC. Results are interpreted in the framework of simplified models featuring gluino and squark production.
