Evolution of open charm production with event multiplicity with ALICE
/ Giacalone, Marco (INFN, Bologna ; Bologna U.)
/ALICE Collaboration
The study of charm production as a function of multiplicity is important to investigate the role of multi-parton interactions, color-reconnection mechanisms, and spectra modification in high multiplicity events with respect to minimum bias ones, and to dig into the possible presence of collective phenomena in high-multiplicity environments.
Moreover, charm cross-section measurements in pp collisions provide a useful test of QCD calculations while measurements in p--Pb collisions are useful to analyze Cold Nuclear Matter effects.
In this contribution, recent measurements of the evolution of the production yields with the event charged-particle multiplicity of prompt D-mesons and leptons from heavy-flavour hadron decays in pp collisions at $\sqrt{s} =$ 13 TeV are discussed. The results are compared to the $\mathrm{J/\Psi}$ measurement and to model calculations. [...]

Charm baryon production and fragmentation fractions in pp collisions with ALICE
/ Seo, Jinjoo (Inha U.)
/ALICE Collaboration
In this contribution, the latest measurements of $\Lambda_\mathrm{c}^+$, $\Xi_\mathrm{c}^{0,+}$, $\Sigma_\mathrm{c}^{0,++}$, and the first measurement of $\Omega_\mathrm{c}^0$ baryons performed with the ALICE detector at midrapidity in pp collisions at $\sqrt{s}=5.02$ and $13\,\rm TeV$ are presented.
In addition, the \Lc measurement down to $p_\mathrm{T}=0$ in p--Pb collisions will be discussed.
Finally, the first measurements of the total charm cross section per unit of rapidity and the fragmentation fractions at midrapidity in pp collisions at the LHC including the charm baryons are discussed..
