Descripción
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 M T2 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. [Figure not available: see fulltext.]
