      abstract     = {The $p_{\rm T}$-differential production cross sections of
                      prompt D$^0$, Λ$_c^+$, and Σ$_c^{0,++}$(2455) charmed
                      hadrons are measured at midrapidity (|y|<0.5) in pp
                      collisions at $\sqrt{s}$=13 TeV. This is the first
                      measurement of Σ$_c^{0,++}$ production in hadronic
                      collisions. Assuming the same production yield for the three
                      Σ$_c^{0,+,++}$ isospin states, the baryon-to-meson cross
                      section ratios Σ$_c^{0,+,++}$/D$^0$ and Λ$_c^+$/D$^0$ are
                      calculated in the transverse momentum ($p_\rm{T}$) intervals
                      $2 < p_{\rm T} < 12$ and $1 < p_{\rm T} < 24$ GeV/$c$.
                      Values significantly larger than in e$^+$e$^-$ collisions
                      are observed, indicating for the first time that baryon
                      enhancement in hadronic collisions also extends to the
                      Σ$_c$. The feed-down contribution to Λ$_c^+$ production
                      from Σ$_c^{0,+,++}$ is also reported and is found to be
                      larger than in e$^+$e$^-$ collisions. The data are compared
                      with predictions from event generators and other
                      phenomenological models, providing a sensitive test of the
                      different charm-hadronization mechanisms implemented in the
                      models.},
