Description
We show that the recent LHC data on transverse-momentum spectra of hadrons produced in PbPb collisions at sqrt(sNN) = 2.76 TeV can be explained by the hadronization out of equilibrium [1,2]. The values of our fit parameters suggest the onset of pion Bose condensation. We determine the number of pions in the condensate and make predictions for the pion spectra at low p_T [3]. We further argue that the Bose condensation has even stronger impact on the fluctuations and correlations of pions [4,5], and present some quantitative estimates of expected effects.
