Search for third-generation scalar leptoquarks decaying to a top quark and a tau lepton at root s=13 TeV

A search for pair production of heavy scalar leptoquarks (LQs), each decaying into a top quark and a τ lepton, is presented. The search considers final states with an electron or a muon, one or two τ leptons that decayed to hadrons, and additional jets. The data were collected in 2016 in proton–p...
