Abstract: A search is presented for direct scalar top pair production where the scalar tops decay via an R-parity-violating coupling to a final state with two leptons and two identified b-jets. The analysis uses 20.3 fb−1 of s√=8 TeV proton-proton collision data collected with the ATLAS detector at the LHC. No significant excess is observed over the Standard Model background. Assuming a supersymmetric minimal B−L extension to the Standard Model, limits on the scalar top mass are placed between 500 GeV and 1 TeV with a branching fraction above 20% for the scalar top to decay to an electron or a muon and a b-quark
