Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks search for supersymmetry in proton-proton ⋯ A. M. SIRUNYAN et al.

A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance pmiss T in transverse momentum. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV,...
