Prompt $\Xi_{\rm c}^{0}$-baryon $p_{\rm T}$-differential cross section in p-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV. The statistical uncertainties are shown as vertical bars and the systematic uncertainties are shown as boxes. Left: comparison to predictions from POWHEG+PYTHIA 6  simulations matched with the EPPS16 nPDF parameterisation, PYTHIA 8 Angantyr calculations, and the QCM. The uncertainties on the POWHEG calculation are due to the choice of the pQCD scales and the charm quark mass as described in the text. Right: Comparison with the cross section measured in the semileptonic decay channel in pp collisions at $\sqrt{s}=5.02$ TeV and in the hadronic decay channel in pp collisions at $\sqrt{s}=13$ TeV scaled to $\sqrt{s}=5.02$ TeV (the energy-scaling factor is described in the text). Both the pp measurements are scaled by the atomic mass number A of the Pb nucleus.
