“…In the region p T & 3 GeV=c (Kraków) and p T & 1:5 GeV=c (HKM) the last two models reproduce the experimental data within $20%, supporting a hydrodynamic interpretation of the transverse momentum spectra at the LHC. These models also describe correctly other features of the space-time evolution of the system, as measured by ALICE with charged pion correlations [46]. In order to quantify the kinetic freeze-out parameters at ffiffiffiffiffiffiffiffi s NN p ¼ 2:76 TeV, we performed a combined fit with a blast wave function [15], with the freezeout temperature T kin , the average transverse velocity h T i, and the exponent of the velocity profile as free parameters.…”

“…The lifetime of about 10 fm/c is about 20% larger than at RHIC. The energy density reached at LHC, about 10 GeV/fm 3 , is three times the one at RHIC. A preliminary measurement of the direct photons spectrum in 0-40% most central Pb-Pb collisions for 0.5-2.5 GeV/c transverse momentum yields a temperature of 304 ± 51 MeV, which is about 40% larger than the one found at RHIC.…”

“…More in details, identical boson interferometry indicates that the freeze-out volume is increased by a factor of two with respect to RHIC, while the lifetime of the fireball is 40% larger [2].…”
