Invariant mass distributions of $\Xi_{\rm c}^{0} \rightarrow {\rm \pi^{+}}\Xi^{-}$ candidates (and charge conjugates) in $2 < \pt< 4$ GeV/$c$ (left), and in $6< \pt< 8$ GeV/$c$ (right) in p-Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV. The red dashed curves represent the background fit functions, and the blue curves represent the total fit functions.
