Left panel: \pt-differential production cross section of prompt $\Xi^0_{\rm c}$ baryons in pp collisions at $\sqrt{s}$ = 5.02 TeV compared with model calculations . Right panel: $\Xi^0_{\rm c}/{\rm D^0}$ ratio as a function of \pt measured in pp collisions at $\sqrt{s}$ = 5.02 TeV compared with model calculations  (see text for details).
