Sylvia Mason (Columbia U.), Probing the Energy Frontier with Top Quarks
by
Top quarks are the heaviest fundamental particle, and their properties
can open up a wealth of new information about the SM and beyond. These
properties have been extensively studied by LHC experiments. In this seminar I will discuss some of the recent ATLAS results and motivate the need to study the top quark more thoroughly at the LHC and beyond. For example, quantum observables such as entanglement have recently been measured in top quark pairs. New searches for t¯t pairs in association with a single Higgs boson (t¯tH) or pairs of Higgs bosons (t¯tHH) are unique ways to probe the top-Higgs sector and could help us better understand the nature of EWSB. Finally, BSM physics can be probed through EFT interpretations in processes involving top quarks.
