PY 2019 BP 144 EP 48pp VL 06 IS 6 DI 10.1007/JHEP06(2019)144 LA English DE Hadron-Hadron scattering (experiments) AB Limits are set on the pair production of scalar leptoquarks, where all possible decays of the leptoquark into a quark (t, b) and a lepton (, ) of the third generation are considered. The limits are presented as a function of the leptoquark mass and the branching ratio into charged leptons for up-type (LQ
