Abstract: The production cross section for prompt open-charm mesons is measured in proton-proton collisions at the LHC center-of-mass energy of 13 TeV. The data sample corresponds to an integrated luminosity of 29 nb $^{-1}$ collected by the CMS experiment in 2016. The differential cross sections of the $\mathrm{D}^{*\pm}$ , $\mathrm{D}^{\pm}$ , and $\mathrm{D}^0$ ( $\mathrm{\bar D^0}$ ) mesons are presented in bins of transverse momentum and pseudorapidity in the range 4 $< p_{\rm T} <$ 100 GeV and $\|\eta\| <$ 2.1, respectively. The results are also compared to several theoretical calculations and to previous measurements.
