We analyze Pb+Pb collisions at √ s NN = 2 . 76 TeV with a novel framework based on the dynamical core– corona picture that describes particle productions from both equilibrium and non-equilibrium components. We remark the possibility of the contribution from non-equilibrium components at very low transverse momentum ( p T ) region and show that such contributions significantly affect p T -integrated four-particle cumulants. These results strongly suggest the necessity of non-equilibrium components when one extracts properties of the quark-gluon plasma from experimental data using sophisticated dynamical models based on relativistic hydrodynamics.
