Invariant mass distributions of $\Lambda_{\rm c}^+$- and $\Xi_{\rm c}^+$-baryon candidates and charge conjugates at low transverse momentum in \pp collisions at $\s=13$ TeV. The blue solid lines show the total fit functions as described in the text and the red dashed lines represent the background The values of the mean ($\mu$) and the peak width ($\sigma$) of the signal peak are reported together with the signal counts (S). The bottom panels report the charm-baryon invariant mass distribution after the subtraction of the background candidates parametrised as detailed in the main text ($S-B$). The Gaussian $\sigma$ are fixed to values from MC simulations. The reported uncertainties are only the statistical uncertainties from the fit.
