Search for leptoquarks decaying into the bτ final state in pp collisions at √s = 13 TeV with the ATLAS detector : = Search for leptoquarks decaying into the b[tau] final state in pp collisions at [square root]s = 13 TeV with the ATLAS detector

Abstract: A search for leptoquarks decaying into the bτ fnal 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 = 13 TeV 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 signifcant excess above the Standard Model prediction is observed, and 95% confdence 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
