New results from the ATLAS Collaboration finds evidence for the production of four top quarks in the LHC collisions, providing a unique opportunity to study the top quark’s relationship to the Higgs boson. The rate of this process could be affected by various new theories that go beyond the Standard Model, providing an exciting window to search for new physics. This talk summarizes the results using proton-proton collision data at a centre of-mass energy of 13 TeV with leptonic final states. Machine learning techniques are used to better discriminate the signal events from the overwhelming background. The observed signal significance is 4.7 standard deviations above the background and is consistent with the Standard Model expectation within 2.0 standard deviations.
