The normalized differential yield of $\Sigma^{+}+\overline{\Sigma}^{-}$ as a function of $p_{\rm T}$ in minimum-bias pp collisions at $\sqrt{s}=13$ TeV (blue symbols) compared with PYTHIA 6 (green line), PYTHIA 8 (purple line), EPOS LHC (red line) and EPOS4 (orange line) generators. The lower panel shows the ratio between the data points and the MC predictions. The statistical uncertainties of the data points are shown as bars and the systematic ones as boxes. The statistical uncertainties of the model predictions are given by the width of the bands.
