Abstract

The production of $D^{\pm}$ and $D_{s}^{\pm}$ charmed mesons is measured using the $D^{\pm} / D_{s}^{\pm} \to ϕ (μμ) π^{\pm}$ decay channel with 137 fb $^{- 1}$ of $s = 13$ TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider during the years 2016-2018. The charmed mesons are reconstructed in the range of transverse momentum $12 < p_{T} < 100$ GeV and pseudorapidity $∣ η ∣ < 2.5$ . The differential cross-sections are measured as a function of transverse momentum and pseudorapidity, and compared with next-to-leading-order QCD predictions. The predictions are found to be consistent with the measurements in the visible kinematic region within the large theoretical uncertainties.
