First study discovers top-quark pair production cross section in lead-lead collisions, suggesting insights into strongly interacting matter.
In relativistic heavy-ion collisions, top quarks are expected to be attractive candidates for probing the quark-gluon plasma as well as to bring unique information about the time evolution of strongly interacting matter. We report the first study of top-quark pair production in lead-lead collisions at the centre-of-mass energy of 5.02 TeV with the ATLAS experiment at the LHC. The dataset was recorded in 2015 and 2018, amounting to an integrated luminosity of 1.9 nb−1. Top-quark pair production cross section is studied in the eμ channel. The result is compared to theory predictions based on different nuclear PDF sets.
