description: Production cross-sections of prompt charm mesons are measured with the first data from $pp$ collisions at the LHC at a centre-of-mass energy of $13\,\mathrm{TeV}$. The data sample corresponds to an integrated luminosity of $4.98 \pm 0.19\,\mathrm{pb}^{-1}$ collected by the LHCb experiment. The production cross-sections of $D^{0}$, $D^{+}$, $D_{s}^{+}$, and $D^{*+}$ mesons are measured in bins of charm meson transverse momentum, $p_{\mathrm{T}}$, and rapidity, $y$, and cover the range $0 &lt; p_{\mathrm{T}} &lt; 15\,\mathrm{GeV}/c$ and $2.0 &lt; y &lt; 4.5$. The inclusive cross-sections for the four mesons, including charge conjugation, within the range of $1 &lt; p_{\mathrm{T}} &lt; 8\,\mathrm{GeV}/c$ are found to be \begin{equation} σ(pp \to D^{0} X) = 2072 \pm 2 \pm 124\,μ\mathrm{b}\\ σ(pp \to D^{+} X) = 834 \pm 2 \pm \phantom{1}78\,μ\mathrm{b}\\ σ(pp \to D_{s}^{+} X) = 353 \pm 9 \pm \phantom{1}76\,μ\mathrm{b}\\ σ(pp \to D^{*+} X) = 784 \pm 4 \pm \phantom{1}87\,μ\mathrm{b} \end{equation} where the uncertainties are due to statistical and systematic uncertainties, respectively.
