Search for direct production of top squark pairs decaying to all-hadronic final states in pp collisions at sqrt(s) = 13 TeV

A search for top squarks in events with jets and missing transverse momentum is presented. The data were collected in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector at the LHC and correspond to an integrated luminosity of 2.3~\ensuremath{\text{fb}^{-1}}. Events are categorized by the properties of reconstructed jets, the presence of top quark candidates, and missing transverse momentum. No statistically significant excess of events above the expected contribution from standard model processes is observed. Exclusion limits are set in the context of simplified models of top squark pair production.
