D-meson production in proton-proton collisions with ALICE at the LHC

Abstract

In this paper, an overview of recent ${\mathrm{D}}^0$, ${\mathrm{D}}^{+}$ and ${\mathrm{D}}^{\ast +}$ measurements, performed by ALICE in proton--proton collisions at $\sqrt{s}=2.76$, 5, 7, 8 and 13 TeV, is reported. The minimum-bias production cross sections, as well as their energy and species dependences, are compared to perturbative QCD calculations. The evolution of the D-meson yields with the event multiplicity is compared to phenomenological models.
