Description
Heavy-flavor quarks (charm and beauty) play an important role in probing the Quark-Gluon Plasma (QGP) formed in the heavy-ion collisions. Due to their heavy masses, charm and beauty quarks are formed in hard scattering processes on a timescale shorter than the QGP formation time at LHC energy. Therefore, they experience all the phases of the medium evolution interacting with the medium constituents and losing energy via collisional and radiative processes. In particular, the mass difference between beauty and charm quarks provides an ideal tool to investigate the predicted mass dependence of parton in-medium energy loss. On this regard, the study of non- prompt $\rm D^0$-meson production in Pb-Pb collisions provides an indirect measurement of beauty quark production, while the same study in pp collisions, besides, providing the needed reference for Pb-Pb studies, is an excellent tool to investigate perturbative Quantum Chromo Dynamics (pQCD) calculations.
In this talk, the latest results on non-prompt $\rm D^0$meson production in Pb-Pb and $p_{\rm{T}}$-differential cross section in pp collision at $\sqrt{s_{\rm{NN}}} = 5.02$ TeV will be shown.
