Description

Heavy quarks (charm and beauty) are a valuable probe to study the properties of the Quark-Gluon Plasma created in Pb--Pb collisions. In order to distinguish the hot nuclear matter effects in Pb--Pb collisions from possible Cold Nuclear Matter effects (CNM), measurements in p--Pb collisions are crucial.
Possible CNM effects, such as $k_{\rm{T}}$-broadening, shadowing and parton energy loss in the cold nuclear matter, are studied via the comparison of the $\rm{D}^{*+}$ yield measured in p--Pb and pp collisions. This comparison is quantified by the nuclear modification factor $R_{\rm{pPb}}$.
Furthermore, studies of the $p_{\rm{T}}$-differential cross-section of $\rm{D}^{*+}$ mesons in pp collisions at the Large Hadron Collider (LHC) allow us to test next-to-leading-order perturbative QCD calculations at the TeV energy regime, while also providing a reference for p--Pb and Pb--Pb measurements.

The $\rm{D}^{*+}$ mesons measured with ALICE at the LHC are reconstructed at mid rapidity via the hadronic channel $\rm{D}^{*+}\to\rm{D}^0\pi^+\to \rm{K}^-\pi^+\pi^+$.
In this contribution, the $\rm{D}^{*+}$-meson production in pp collisions collected in Run I at $\sqrt{s}=8$ TeV will be presented, as well as the latest Run II results for the $\rm{D}^{*+}$-meson production in pp collisions at $\sqrt{s}=13$ TeV and p--Pb collisions at $\sqrt{s_{\rm{NN}}}=5.02$ TeV.
