The analysis relies on the identification of b-jets and high missing transverse momentum to achieve good sensitivity. A data sample of protonproton collisions at √s = 13 TeV recorded with the ATLAS detector at the Large Hadron Collider in 2015 and 2016, corresponding to a total integrated luminosity of 36.1 fb-1, is used for the search. No significant excess over the Standard Model prediction is observed. The results are interpreted in several simplified supersymmetric models featuring R-parity conservation or R-parity violation, extending the exclusion limits from previous searches. In models considering gluino pair production, gluino masses are excluded up to 1.87 TeV at 95% confidence level. When bottom squarks are pair-produced and decay to a chargino and a top quark, models with bottom squark masses below 700 GeV and light neutralinos are excluded at 95% confidence level. In addition, model-independent limits are set on a possible contribution of new phenomena to the signal region yields.}, organization = {CERN}, organization = {MINECO}, organization = {EPLANET}, organization = {ERC}, organization = {ERDF}, organization = {FP7}, organization = {Horizon 2020}, organization = {Marie Skłodowska-Curie Actions}, organization = {CERCA Programme Generalitat de Catalunya}, organization = {Generalitat Valenciana}, publisher = {Springer Nature}, keywords = {Hadron-Hadron scattering (experiments)}, keywords = {Supersymmetry}, title = {Search for supersymmetry in final states with two same-sign or three leptons and jets using 36 fb-1 of √s = 13 TeV pp collision data with the ATLAS detector}, doi = {10.1007/JHEP09(2017)084}, author = {Aaboud, M. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration, /}, }
