The data were collected with the CMS detector at the CERN LHC in 2016 and 2017, and correspond to an integrated luminosity of 77.4fb?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-pTstandard 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 pTmuon and jet. The data are observed to be consistent with the background predicted by the standard model. For the first benchmark scenario considered, dark matter masses up to 500GeV are excluded for leptoquark masses mLQ?1400GeV, and up to 300GeV for mLQ?1500GeV. For the second benchmark scenario, dark matter masses up to 600GeV are excluded for mLQ?1400GeVenCMSPhysicsDark matterLeptoquarksArticle10.1016/j.physletb.2019.05.0462-s2.0-85066999169Q1WOS:000477924000010Q1
