PWG-MM (Monte Carlo generators and Minimum Bias)
Kaon-to-pion and proton-to-pion ratios as a function of \pt for two \RT intervals: $0 \leq \RT < 0.5$ (red markers) and $2.5 \leq \RT < 5$ (blue markers). The particle ratios in the toward, away and, transverse regions are shown from left to right. The PYTHIA 8 Monash and PYTHIA 8 ropes (EPOS LHC and Herwig) predictions are shown in the top (bottom) figure. The shaded regions around the model line represent the statistical uncertainties.
