Description

The heavy-flavor quarks (charm, beauty) play an important role in probing the Quark-Gluon Plasma (QGP) formed in the heavy-ion collisions. They are produced in hard partonic scattering processes, and have shorter formation time than the QGP. As a result, they experience all the phases of the plasma evolution propagating through the QGP and losing energy interacting with its constituents. Therefore, measuring heavy-flavor hadron production helps us understanding heavy-quark mass-dependent in-medium energy loss and their hadronization mechanism.

In this regard, the study of non-prompt D$^0$-meson production in Pb-Pb collisions provides an indirect measurement in the beauty sector, while the same study in pp collisions, beside providing the needed reference for Pb-Pb studies, is an excellent tool to investigate perturbative Quantum ChromoDynamics (pQCD) calculations.

This poster shows the production cross section of non-prompt D$^0$ mesons (b→c→D$^0$) at mid-rapidity, measured in pp collisions at $\sqrt{s}$ = 5.02 TeV collected with the ALICE detector.
