Search for direct production of supersymmetric partners of the top quark in the all-jets final state in proton-proton collisions at √s=13 TeV

A search for direct production of top squark pairs in events with jets and large transverse momentum imbalance is presented. The data are based on proton-proton collisions at a center-of-mass energy of 13 TeV, collected with the CMS detector in 2016 at the CERN LHC, and correspond to an integrate...
