The proton/pion ratio (left) and kaon/pion ratio (right), as measured by ALICE using TPC and TOF (filled symbols), compared with the standard priors as described in the text (open symbols) for Pb-Pb and p-p collisions. For Pb-Pb, the results are reported for different centrality classes. Particle ratios are calculated for mid-rapidity, $|y|< 0.5$. The double ratios (the measured abundances divided by the Bayesian priors) are shown in the lower panels. | |
