Top-quark pair production in Pb+Pb collisions in the ATLAS experiment / Potepa, Patrycja Anna (AGH University of Krakow (PL))
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. [...]
