Description
Heavy flavour hadrons are key probes for the investigation of the initial stage as well as the evolution of the system created in heavy-ion collisions. In fact, the heavy quarks possess masses larger than the quantum chromodynamics (QCD) scale parameters and therefore are mainly produced in hard scattering processes with large momentum transfer $Q^2$. For the same reason, their production in proton-proton (pp) collisions can be described by perturbative QCD calculations. In addition, the measurement of heavy-flavour hadrons as a function of the charged-particle multiplicity in pp collisions provides insights in the interplay between soft and hard processes and multi-parton interactions.
In this contribution, the first measurement of $D^{*\pm}$ production in different multiplicity classes using the large data sample of pp collisions at $\sqrt{s}$ = 13.6 TeV collected by the ALICE experiment during the LHC Run3, are presented. This includes the measurement of the $p_{\rm T}$-differential production cross section as well as the yield in different charged-particle multiplicity classes. Also, these results will be compared with lower LHC energies measurements.
