Descripción
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-proton collisions at √{s}=13 {Te} {V}
with the CMS detector at the LHC, and correspond to an integrated
luminosity of 35.9 {fb}^{-1}. No evidence for pair production of LQs is
found. Assuming a branching fraction of unity for the decay LQ →
tτ , upper limits on the production cross section are set as a
function of LQ mass, excluding masses below 900 {Ge} {V} at 95%
confidence level. These results provide the most stringent limits to
date on the production of scalar LQs that decay to a top quark and a
τ lepton.
