| Abstract: A search for t-channel exchange of leptoquarks (LQs) is performed using proton-proton collision data collected at √s= 13 TeV with the CMS detector at the CERN LHC. The data correspond to an integrated luminosity of 138 fb−1. The search spans scenarios with scalar and vector LQs that couple up and down quarks to electrons and muons. Dielectron and dimuon final states are considered, with dilepton invariant masses above 500 GeV. The differential distributions of dilepton events are fit to templates built from reweighted samples of simulated standard model events. This method is able to probe higher LQ masses than previous pair-production and single-production searches. Limits are set on LQ-fermion coupling strengths for LQ masses up to 5 TeV. Based on the results, scalar LQs are excluded for masses up to 5 TeV for a coupling strength of 1.2, and vector LQs are excluded for masses up to 5 TeV for a coupling strength of 1.5. | ||
