A search for new phenomena is performed in final states containing one
or more jets and an imbalance in transverse momentum in pp collisions at
a centre-of-mass energy of 13TeV" role="presentation">TeV. The analysed data sample, recorded with the CMS detector at the CERN LHC, corresponds to an integrated luminosity of 2.3fb−1" role="presentation">fb−1.
Several kinematic variables are employed to suppress the dominant
background, multijet production, as well as to discriminate between
other standard model and new physics processes. The search provides
sensitivity to a broad range of new-physics models that yield a stable
weakly interacting massive particle. The number of observed candidate
events is found to agree with the expected contributions from standard
model processes, and the result is interpreted in the mass parameter
space of fourteen simplified supersymmetric models that assume the pair
production of gluinos or squarks and a range of decay modes. For models
that assume gluino pair production, masses up to 1575 and 975GeV" role="presentation">GeV
are excluded for gluinos and neutralinos, respectively. For models
involving the pair production of top squarks and compressed mass
spectra, top squark masses up to 400GeV" role="presentation">GeV are excluded.
