Searches for pair production of charginos and top squarks in final states with two oppositely charged leptons in proton-proton collisions at √s=13 TeV

A search for pair production of supersymmetric particles in events with two oppositely charged leptons (electrons or muons) and missing transverse momentum is reported. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of protonproton collisions at √ s = 13 TeV collected with t...
