title: "Figure 9 D0 ratio pp 13 TeV over pp 5.02 TeV" of "Charm production and fragmentation fractions at midrapidity in pp collisions at $\sqrt{s} = 13$ TeV"

description: $\sigma(\mathrm{D}^{0})$ $\sqrt{s}$ = 13 TeV / $\sigma(\mathrm{D}^{0})$ $\sqrt{s}$ = 5.02 TeV
description: Measurements of the production cross sections of prompt $\mathrm{D}^0$, $\mathrm{D}^+$, $\mathrm{D}^{*+}$, $\mathrm{D}^+_\mathrm{c}$, $\Lambda^+_\mathrm{c}$, and $\Xi^+_\mathrm{c}$ charm hadrons at midrapidity in proton$-$proton collisions at $\sqrt{s}=13$ TeV with the ALICE detector are presented. The D-meson cross sections as a function of transverse momentum ($p_\mathrm{T}$) are provided with improved precision and granularity. The ratios of $p_\mathrm{T}$-differential meson production cross sections based on this publication and on measurements at different rapidity and collision energy provide a constraint on gluon parton distribution functions at low values of Bjorken-$x$ ($10^{-5}-10^{-4}$). The measurements of $\Lambda^+_\mathrm{c}$ ($\Xi^+_\mathrm{c}$) baryon production extend the measured $p_\mathrm{T}$ intervals down to $p_\mathrm{T}=0(3)$~GeV$/c$. These measurements are used to determine the charm-quark fragmentation fractions and the $\mathrm{c}\bar{\mathrm{c}}$ production cross section at midrapidity ($|y|&lt;0.5$) based on the sum of the cross sections of the weakly-decaying ground-state charm hadrons $\mathrm{D}^0$, $\mathrm{D}^+$, $\mathrm{D}^+_\mathrm{c}$, $\Lambda^+_\mathrm{c}$, $\Xi^0_\mathrm{c}$ and, for the first time, $\Xi^+_\mathrm{c}$, and of the strongly-decaying $J/\psi$ mesons. The first measurements of $\Xi^+_\mathrm{c}$ and $\Sigma_\mathrm{c}^{0,+,++}$ fragmentation fractions at midrapidity are also reported. A significantly larger fraction of charm quarks hadronising to baryons is found compared to $\mathrm{e}^+\mathrm{e}^-$ and ep collisions. The $\mathrm{c}\bar{\mathrm{c}}$ production cross section at midrapidity is found to be at the upper bound of state-of-the-art perturbative QCD calculations.
