Özet
A search is presented for dark matter in proton-proton collisions at a center-of-mass energy of s= 13 TeV using events with at least one high transverse momentum (p T) muon, at least one high-p T jet, and large missing transverse momentum. The data were collected with the CMS detector at the CERN LHC in 2016 and 2017, and correspond to an integrated luminosity of 77.4 fb− 1. In the examined scenario, a pair of scalar leptoquarks is assumed to be produced. One leptoquark decays to a muon and a jet while the other decays to dark matter and low-p T standard model particles. The signature for signal events would be significant missing transverse momentum from the dark matter in conjunction with a peak at the leptoquark mass in the invariant mass distribution of the highest p T muon and jet. The data are observed to be consistent with the background predicted by the standard model. For the first benchmark …
