Spectra of $\overline{\Sigma}^{+}$ (left column) and $\overline{\Sigma}^{-}$ (right column) measured in pp (top row) and p--Pb (bottom row) collisions at $\sqrt{s_{\rm{NN}}} = 5.02 \text{TeV}$ compared to predictions of EPOS LHC and EPOS4 , PYTHIA 8 , PHOJET and DPMJET  models. Also, Lévy-Tsallis fits to the measured spectra are shown. All models except EPOS4 have negligible statistical uncertainties. The uncertainties of the models are included as statistical ones in the data to MC ratio.
