Description
Heavy quarks (charm and beauty) have masses much larger than the QCD scale parameter. Due to this they are typically produced in hard scattering processes with large Q^2 in hadronic collisions, and offer a unique perspective to study the transition from quark to hadrons in these collision systems. Recent production measurements of heavy-flavour baryons and mesons in proton-proton collisions at midrapidity show heavy-flavour baryon-to-meson ratios significantly higher than those measured in e+e− collisions, which challenges the universality of fragmentation functions across different collision systems. Thus, further and more precise measurements of heavy-flavour production-yield ratios are crucial to study the heavy quark hadronization in a partonic rich environment like the one produced in pp collisions at the LHC energies. In p–Pb collisions, a modification of the hadronization mechanisms could be present due to cold nuclear matter effects and possible collective
phenomena.
In this contribution, measurements of the meson-to-meson and meson-to-baryon ratios withALICE in pp and p–Pb collisions will be shown. A systematic comparison between data and models will help to understand heavy-quark hadronization in pp and p–Pb collisions. To conclude, the first studies of heavy-flavour hadron reconstruction using large data sample of pp collisions at √s = 13.6 TeV from Run 3 will also be presented.
