Abstract: Highly energetic top quarks produced in proton-proton collisions at the LHC can result in decay products that are highly collimated, appearing as a single large-radius jet in the CMS detector. These jets exhibit a distinctive internal substructure, enabling discrimination between top quark jets and those arising from other QCD processes. However, discrepancies between distributions in recorded data and simulations require corrections to the simulations. The boosted topology offers a unique opportunity to probe for new heavy particles decaying into top-antitop quark pairs. This presentation provides first insights from the ongoing LHC Run 3, focusing on the top-antitop quark mass spectrum as a potential window to new physics phenomena.
