ATLAS performed various searches for supersymmetric squarks and gluinos decaying into different final states containing leptons, jets, b-tagged jets, and missing transverse momentum. The analyses use a data sample collected during 2015, which corresponds to a total integrated luminosity of 3.2 fb−1 of 13 TeV proton-proton collisions. The results from these searches are interpreted in a variety of simplified models featuring gluino production. The experimental sensitivity reached gluino masses up to 1.6 TeV in the leptonic channels.
