A search for direct production of top squark pairs in proton-proton collisions with a center-of-mass energy of 13 TeV is presented for two scenarios each requiring jets and a large transverse momentum imbalance.
The two scenarios include, a ``low Delta m'' analysis targeting very small mass differences between the top squark and the neutralino, and a ``high Delta m'' analysis targeting topologies typical for larger mass splittings.
Using data collected during operations in 2015 corresponding to an integrated luminosity of 12.9 fb^(-1), no significant excess of events above the expected standard model background processes is observed.
Exclusion limits are set in the context of simplified models of top squark pair production under various decay hypotheses.
