Description

This poster presents a search for pair-produced scalar leptoquarks decaying to leptons and hadronic top quarks using 139 fb-1 of data recorded by the ATLAS detector at √s = 13 TeV. As well as being predicted by various extensions of the Standard Model to describe the similarity between the quark and lepton sectors, leptoquarks provide a promising explanation for anomalies observed in both the lepton universality tests in B decays and muon anomalous magnetic moment measurement. Searches for pair-produced scalar leptoquarks decaying to electron-top or muon-top pairs have been performed in final states with exactly two leptons. A parameterized gradient boosted decision trees approach is used to suppress the standard model background. Improved exclusion limits are set on the leptoquark masses are set at 95% confidence level.
