abstract = {A search for leptoquarks decaying into the bτ final state is performed using
Run 2 proton-proton collision data from the Large Hadron Collider, corresponding to an
integrated luminosity of 139 fb−1 at √
s = 13TeV recorded by the ATLAS detector. The
benchmark models considered in this search are vector leptoquarks with electric charge of
2/3e and scalar leptoquarks with an electric charge of 4/3e. No significant excess above the
Standard Model prediction is observed, and 95% confidence level upper limits are set on
the cross-section times branching fraction of leptoquarks decaying into bτ . For the vector
leptoquark production two models are considered: the Yang-Mills and Minimal coupling
models. In the Yang-Mills (Minimal coupling) scenario, vector leptoquarks with a mass
below 1.58 (1.35)TeV are excluded for a gauge coupling of 1.0 and below 2.05 (1.99)TeV
for a gauge coupling of 2.5. In the case of scalar leptoquarks, masses below 1.28 (1.53)TeV
are excluded for a Yukawa coupling of 1.0 (2.5). Finally, an interpretation of the results
with minimal model dependence is performed for each of the signal region categories, and
limits on the visible cross-section for beyond the Standard Model processes are provided.},
