Searches for Leptoquarks with the ATLAS detector

Leptoquarks are hypothetical particles that appear in many theoretical extensions of the Standard Model. They are predicted to mediate interactions between quarks and leptons, bridging the gap between the two fundamental classes of particles. Other theoretical models, such as supersymmetry, introduce a link between bosons and fermions, predicting additional particles such as stops. Both extensions offer a compelling avenue for exploring new physics beyond the Standard Model and have the potential to explain a variety of experimental observations. Decays of supersymmetric particles and leptoquarks decay to neutrinos lead to a characteristic shared signature of missing energy, allowing for a straightforward interpretation of searches in both models. The ATLAS experiment at the Large Hadron Collider is conducting a comprehensive program of searches for leptoquarks and supersymmetric particles, targeting interactions with particles from all three generations. This talk will present the most recent results from the ATLAS collaboration's search for leptoquarks and stops in various experimental signatures, including flavour-diagonal and cross-generational final states.
