$\Sigma_{c}^{0,+,++}/\Xi_{c}^{0,+}$ ratio as a function of $\it{p}_\mathrm{T}$ in pp collisions at 13 TeV. The numerator corresponds to the $\Sigma_{c}^{0,++}$ cross section multiplied by 3/2. The denominator corresponds to the sum of $\Xi_{c}^{0}$ and $\Xi_{c}^{+}$ cross sections for $\it{p}_\mathrm{T}>$4 GeV/$c$ and to $2\times\Xi_{c}^{0}$ cross section for $2<\it{p}_\mathrm{T}<$4 GeV/$c$. Statistical uncertainties (bars) and systematic uncertainties (empty boxes) are shown. The systematic uncertainties related to branching ratio uncertainties are shown separately (shaded boxes). The measurement is compared with Pythia Monash 2013 (black), Pythia Mode 0 (blue), Pythia Mode 2 (red) Pythia Mode 3 (violet).
