Search for strongly produced supersymmetric particles in final states with two same-sign leptons and jets with the ATLAS detector using 21 fb$^{−1}$ of pp collisions at 8 TeV

A search for the production of supersymmetric (SUSY) particles decaying into final states with jets, b -jets, missing transverse momentum and two isolated leptons, e or m , with the same electric charge (same-sign leptons) is presented. The analysis uses a data sample collected during 2012, which corresponds to a total integrated luminosity of 20.7 fb
