Abstract

A search for dark matter particles is performed using events with large miss- ing transverse momentum, at least one energetic jet, and no leptons, in proton-proton collisions at √s = 13 TeV collected with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 12.9fb−1. The search includes events with jets from the hadronic decays of a W or Z boson. The data are found to be in agreement with the predicted background contributions from standard model processes. The results are presented in terms of simplified models in which dark matter particles are produced through interactions involving a vector, axial-vector, scalar, or pseudoscalar mediator. Vector and axial-vector mediator particles with masses up to 1.95 TeV, and scalar and pseudoscalar mediator particles with masses up to 100 and 430GeV respectively, are excluded at 95% confidence level. The results are also interpreted in terms of the invisible decays of the Higgs boson, yielding an observed (ex
