Differential cross-sections for \subref{fig:lhcb:Dz:a} $ D ^0$ , \subref{fig:lhcb:Dp:b} $ D ^+$ , \subref{fig:lhcb:dstar:a} $ D ^{*+}$ , and \subref{fig:lhcb:Dsp:b} $ D ^+_ s $ meson production compared to theoretical predictions. The cross-sections for different $y$ regions are shown as functions of $p_{\rm T}$ . The $y$ ranges are shown as separate curves and associated sets of points scaled by factors $10^{-m}$, where the exponent $m$ is shown on the plot with the $y$ range. The error bars associated with the data points show the sum in quadrature of the statistical and total systematic uncertainty. The shaded regions show the range of theoretical uncertainties for the GMVFNS prediction. \label{fig:lhcb:Dp} \label{fig:lhcb:dstar} \label{fig:lhcb:Dsp}

Differential cross-sections for $\Lambda _ c ^+$ baryon production compared to the theoretical prediction from the GMVFNS scheme. The error bars associated with the data points show the sum in quadrature of the statistical and total systematic uncertainty.

Overview of systematic uncertainties and their values, expressed as relative fractions of the cross-section measurements in percent (%). Uncertainties that are computed bin-by-bin are expressed as ranges giving the minimum to maximum values of the bin uncertainties. The correlated and uncorrelated uncertainties are shown as discussed in the text.

Open charm production cross-sections in the kinematic range $ 0 < p_{\rm T} < 8 {\mathrm{ Ge V /}c} $ and $ 2.0 < y < 4.5$ . The computation of the extrapolation factors is described in the text. The first uncertainty is statistical, the second is systematic, and the third is the contribution from the extrapolation factor.

Correlation matrix of the uncertainties of the integrated open charm production cross-sections in the kinematic range $ 0 < p_{\rm T} < 8 {\mathrm{ Ge V /}c} $ and $ 2.0 < y < 4.5$ . The first column restates measured values of the integrated cross-sections .

Cross-section ratios for open charm production in the kinematic range $ 0 < p_{\rm T} < 8 {\mathrm{ Ge V /}c} $ and $ 2.0 < y < 4.5$ . The numbers in the table are the ratios of the respective row/column.
