Combination of searches for pair-produced leptoquarks at √𝑠 =13 TeV with the ATLAS detector

A statistical combination of various searches for pair-produced leptoquarks is presented, using the full LHC Run 2 (2015-2018) data set of 139 fb−1 collected with the ATLAS detector from proton-proton collisions at a centre-of-mass energy of s=13 TeV. All possible decays of the leptoquarks into quar...

Description
Summary:A statistical combination of various searches for pair-produced leptoquarks is presented, using the full LHC Run 2 (2015-2018) data set of 139 fb−1 collected with the ATLAS detector from proton-proton collisions at a centre-of-mass energy of s=13 TeV. All possible decays of the leptoquarks into quarks of the third generation and charged or neutral leptons of any generation are investigated. Since no significant deviations from the Standard Model expectation are observed in any of the individual analyses, combined exclusion limits are set on the production cross-sections for scalar and vector leptoquarks. The resulting lower bounds on leptoquark masses exceed those from the individual analyses by up to 100GeV, depending on the signal hypothesis.
