Search for electroweak production of supersymmetric particles in multileptons final states at LHC Run 2 with the ATLAS detector.
Supersymmetry is one of the most motivated Standard Model extensions. Despite the search during the LHC Run I, there is no evidence supporting this theory. LHC is performing a second data taking with a higher center-of-mass energy, providing a great occasion for the search of beyond the Standard Model physics. New results obtained with the 2015-2016 ATLAS detector data will be presented. The direct production of electroweakinos, with leptons and missing transverse momentum in the final state, is considered. A good sensitivity is obtained in the signal region for supersymmetric particles masses beyond the Run 1 limits.
