Search for leptoquarks at the ATLAS experiment — •Mahsana Haleem for the ATLAS collaboration — Julius-Maximillian-Universität Würzburg, Germany

The leptoquarks predicted in the extensions of physics beyond the Standard Model can describe the similarities between the lepton and quark generations. In the past years, these particles have been the most popular explanations for the B-anomalies reported in low-energy data, and the searches for leptoquarks have been among the important goals of the ATLAS program. Recent results from the LHCb collaboration reporting the disappearance of lepton flavour anomalies in the B-meson decays into kaon and charged-lepton pairs do not affect the search program. They probe unique signatures at the LHC, as they provide direct transitions between leptons and quarks. I will review some of these searches with ATLAS Run-2 dataset and their prospects in Run-3, particularly focusing on the final states with third-generation quarks, which offer great potential to the SM background reductions but are also challenging in terms of the remaining background modeling.
