 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.

 Measurement of electroweak-boson production in Pb–Pb and p–Pb collisions at the LHC / Zhao, M (Beijing, Inst. Atomic Energy) /ALICE Collaboration Electroweak W± and Z bosons are powerful probes of the initial stage of the heavy-ion collisions. The measurements of their production is important to disentangle the effects of initial stage from the effects of the presence of the quark–gluon plasma (QGP).

 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.. 2021 - 5 p. - Published in : PoS CHARM2020 (2021) 023 Fulltext: PDF; In : 10th International Workshop on Charm Physics (CHARM 2020), Online, Mexico, 31 May - 4 June 2021, pp.023

 Charm jet and correlation measurements with ALICE in pp and p -- Pb collisions at the LHC / Palasciano, Antonio (Bari U. ; INFN, Bari) /ALICE Collaboration The recent results about charm jet and correlation measurements by the ALICE experiment are presented in this contribution. The measurements of the $\mathrm{D}^0$ parallel jet momentum fraction in pp collisions at $\sqrt{s}=5.02$ and $13$ TeV are shown and compared with Monte Carlo model predictions.

 Charmonium production in proton-proton and proton-lead collisions with ALICE / Saetre, Jon-Are (Bergen U.) /ALICE Collaboration Charmonium production studies in hadronic collisions are a powerful tool for improving our understanding of quantum chronodynamics (QCD), the theory of the strong interaction. The production of the charm-quark pair can be described within perturbative QCD, whereas the evolution of this pair into a colorless bound state involves soft scale processes.

 Charmonium production as a function of charged-particle multiplicity in pp and p--Pb collisions with ALICE at the LHC / Tork, Theraa Heavy quarkonium production is an excellent tool to test both perturbative and non-perturbative QCD, as perturbative QCD can describe the heavy quark production process, while the formation of the quarkonium bound state involves non-perturbative aspects.
