pT-integrated (Xi- + anti-Xi+)/phi ratio in pp collisions at 13 TeV in V0M multiplicity event classes, p-Pb collisions at 5.02 TeV in V0A multiplicity event classes, and Pb-Pb collisions at 5.02 TeV in centrality classes. Statistical uncertainties are represented by bars and total systematic uncertainties by open boxes. Shaded boxes represent the component of the systematic uncertainty that is uncorrelated between multiplicity classes. The p-Pb data are from Phys. Lett. B 758 389-401 (2016) and Eur. Phys. J. C 76 245 (2016).
