Abstract
The large production of the heavy charm and bottom quarks in heavy-ion collisions over that in $p\phantom{\rule{0}{0ex}}p$ collisions provides key signatures of the formation of the hot and strongly interacting phase known as the quark-gluon plasma. This paper reports on calculations of yields of ${B}_{c}^{+}$ mesons, consisting of a bottom and a charm quark, in Pb + Pb collisions at 5.02 TeV/nucleon at the LHC. The authors compare the results of their transport model with recent CMS data and attribute the observed enhancement to recombination processes of heavy quarks with large phase-space densities in a quark-gluon plasma.
