A search for new physics is performed using events that contain one or more
jets, no isolated leptons, and a large transverse momentum imbalance, as measured through
the MT2 variable, which is an extension of the transverse mass in events with two invisible
particles. The results are based on a sample of proton-proton collisions collected at a
center-of-mass energy of 13 TeV with the CMS detector at the LHC, and that corresponds
to an integrated luminosity of 2.3 fb−1
. The observed event yields in the data are consistent
with predictions for the standard model backgrounds. The results are interpreted using
simplified models of supersymmetry and are expressed in terms of limits on the masses
of potential new colored particles. Assuming that the lightest neutralino is stable and
has a mass less than about 500 GeV, gluino masses up to 1550–1750 GeV are excluded at
95% confidence level, depending on the gluino decay mechanism. For the scenario of direct
production of squark-antisquark pairs, top squarks with masses up to 800 GeV are excluded,
assuming a 100% branching fraction for the decay to a top quark and neutralino. Similarly,
bottom squark masses are excluded up to 880 GeV, and masses of light-flavor squarks are
excluded up to 600–1260 GeV, depending on the degree of degeneracy of the squark masses
