dc.description.abstractA search is presented for a singly produced third-generation scalar leptoquark decaying to a lepton and a bottom quark. Associated production of a leptoquark and a lepton is considered, leading to a nal state with a bottom quark and two leptons. The search uses proton-proton collision data at a center-of-mass energy of 13TeV recorded with the CMS detector, corresponding to an integrated luminosity of 35.9 fb􀀀1. Upper limits are set at 95% con dence level on the production cross section of the third-generation scalar leptoquarks as a function of their mass. From a comparison of the results with the theoretical predictions, a third-generation scalar leptoquark decaying to a lepton and a bottom quark, assuming unit Yukawa coupling ( ), is excluded for masses below 740 GeV. Limits are also set on of the hypothesized leptoquark as a function of its mass. Above = 1:4, this result provides the best upper limit on the mass of a third-generation scalar leptoquark decaying to a lepton and a bottom quark.en
