Kaon to Pion and Proton to Pion ratio in Pb-Pb 5.02 TeV 20-40% centrality (with comparison to hydro models)
Logarithmic scale on the X axis is used to highlight the low pT region.
Detail description
Kaon to Pion (left) and Proton to Pion (right) ratio in Pb-Pb semi-peripheral (20-40%) collisions at sqrt(s_NN) = 5.02 TeV compared to hydro models. The hydro models that have been used are:
- iEbE-VISHNU with TRENTo and AMPT initial conditions (https://arxiv.org/abs/1703.10792)
- EPOS-LHC (Phys. Rev. C 92, 034906 (2015))
- McGill with IP-Glasma initial conditions (https://arxiv.org/abs/1609.02958)
The Data/Model ratios are shown in the bottom panels.
