About
With more than a hundred million pairs of top quarks, the LHC is a top quark factory. Three recent ATLAS measurements that exemplify the unprecedented experimental precision and new, novel analysis methods to reduce uncertainties are presented. This seminar will discuss the ATLAS+CMS combination of top quark mass measurements using the Run 1 of the LHC, resulting in the most precise experimental result to date of this parameter, and that of the measurement of the production of top quark pairs in association with a Z boson, resulting in a precision measurement of the top-Z coupling. Finally, the first observation of quantum entanglement in quarks, as measured with top-quark pairs, and at high energies will be presented. Together, these results highlight the breadth of the top-quark research program at the LHC.
