Inclusive search for supersymmetry in pp collisions at √s = 13 TeV using razor variables and boosted object identification in zero and one lepton final states

An inclusive search for supersymmetry (SUSY) using the razor variables is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 35.9 fb−1 , collected with the CMS experiment in 2016 at a center-of-mass energy of √ s = 13 TeV. The search looks for...
