Nuclear modification factor $R_\mathrm{pPb}$ of prompt $\mathrm{\Xi_c^0}$ baryons in p-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV as a function of $p_{\rm T}$ compared to the $R_\mathrm{pPb}$ of $\mathrm{\Lambda_c^+}$ baryons. The measured $R_\mathrm{pPb}$ is also compared to POWHEG+PYTHIA 6 with EPPS16 simulations, to PYTHIA 8 Angantyr calculations, and to QCM predictions. The statistical uncertainties are shown as vertical bars and the systematic uncertainties are shown as boxes. The uncertainties on the POWHEG calculation are due to the choice of the pQCD scales as described in the text.
