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

TL;DR

This paper reports on measurements of D-meson production in proton-proton collisions at various energies using ALICE, comparing results to QCD calculations and models of event multiplicity dependence.

Contribution

It provides a comprehensive overview of D-meson production data across multiple energies and compares these to theoretical predictions and phenomenological models.

Findings

D-meson cross sections agree with perturbative QCD within uncertainties.

D-meson yields increase with event multiplicity, matching model predictions.

Energy dependence of D-meson production is characterized across different collision energies.

Abstract

In this paper, an overview of recent $\mathrm D^{0}$, $\mathrm D^{+}$ and $\mathrm D^{*+}$ 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.
