Description

Measurements of heavy-flavour (charm and beauty quark) production in proton-proton (pp) collisions as a function of the charged-particle multiplicity are important in order to gain more insight on which processes are involved in the collision at a partonic level. These measurements also provide information on the interplay between hard and soft mechanisms during particle production.

We report on heavy-quark production as a function of the charged-particle multiplicity using data collected in pp collisions with the ALICE detector during the LHC Run 2 at $\sqrt{s} =5.02$ TeV. This study is essential for reference measurements for p-Pb and Pb-Pb systems. The measurement will also probe the role of multi-parton interactions (MPIs) in the production of heavy quarks and investigate whether collective effects play a role in particle production as already observed in other collision systems (p-Pb and Pb-Pb) at different center-of-mass energies. In addition, the study will be used to test QCD-based theoretical models.
