Out-Of-Equilibrium Transverse Momentum Spectra of Pions at LHC Energies

Figure 1

Number of positive pions per transverse momentum per rapidity is given dependent on the transverse momentum. The symbols refer to the ALICE measurements in the most central () Pb+Pb collisions at TeV. The left-hand panel shows a comparison with (10) at vanishing and finite GeV [41]. In middle and right-hand panels, HRG calculations (10), with and without scalar states and excluded volume corrections are confronted to the experimental measurements, as well.
