| Annotation | We fit the single-hadron transverse-momentum spectra measured in Pb+Pb collisions at root sNN = 2.76 TeV with the blast-wave model that includes production via resonance decays. Common fit to pions, kaons, (anti)protons, and lambdas yields centrality dependence of the freeze-out temperature and transverse expansion velocity. In the most central collisions we see T = 98 MeV and nu(t) = 0.654. The K* resonance fits into this picture but the phi meson might freeze-out a little earlier. Multi-strange baryons seem to decouple at higher temperature and weaker transverse flow. Within our model we observe hints of chemical potential for the charged pions. |
