Description
Measurements of charm baryon and meson production in pp and p–Pb minimum bias collisions and as a function of multiplicity, help to investigate hadronization processes and to study their modification across the collision systems from pp to Pb–Pb, and from low to high multiplicities.
Recent measurements of the fragmentation fractions of charm hadrons in pp and p–Pb challenge the universality of fragmentation in the presence of a hadronic medium. In addition, the ratio of $p_\mathrm{T}$ spectra of $\mathrm{\Lambda_c^+/D^0}$ in pp collisions, shows a separation between the highest and the lowest multiplicity classes within $5.3\sigma$, with the maximum discrepancy occurring for $2\ \mathrm{GeV}/c
