 < p>Charm-quark fragmentation-fraction ratio $\f{s}/(\f{u}+\f{d})$ compared with previous measurements performed by the ALICE~, H1~, ZEUS~, and ATLAS~ Collaborations and to the average of LEP measurements~. The total experimental uncertainties (bars) and the theoretical uncertainties (shaded boxes) are shown. The experimental measurements are compared to the value obtained from PYTHIA~8 simulations with Monash-13 tune ~.< /p>
