Production measurements of heavy quarks in pp collisions at $\sqrt{s}$ = 13 TeV with the ALICE detector

Abstract

Heavy-flavour production measurements in pp collisions are important tools to test theoretical models based on perturbative quantum chromodymanics (pQCD) and to investigate the heavy-quark hadronization mechanisms. In ALICE, heavy quarks are measured via the hadronic and electronic decay channels at central rapidity (-0.9 $<$ $\text{y}$ $<$ 0.9) and via the muon decay channels at forward rapidity (-4 $<$ $\text{y}$ $<$ -2.5). In this contribution, the production cross-section measurements via the leptonic decay of heavy-flavour hadrons are presented and compared to pQCD theoretical calculations. The latest measurements of ${\mathrm{D}}^0$, ${\mathrm{D}}^{+}$, ${\mathrm{D}}^{\ast +}$, $D_s^{+}$ mesons whose hadronic decays into charged are fully reconstructed together with the measurements of ${\Lambda }_c^{+}$ , ${\Xi }_c^{0,+}$, ${\Sigma }_c^{0,++}$ and ${\Omega }_c^0$ baryons, performed with the ALICE detector at midrapidity in pp collisions at $\sqrt{s}$ = 13 TeV, are also presented. Measurements of charm-baryon production are crucial to study the charm-quark hadronization mechanisms in a partonic rich environment like the one produced in pp collisions at LHC energies.
