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…

Recent theory progress in (3+1)D dynamical descriptions of relativistic nuclear collisions at finite baryon density are reviewed. Heavy-ion collisions at different collision energies produce strongly

Enhancement of strange baryons in high-multiplicity proton–proton and proton–nucleus collisions

We investigate the enhancement of yields of strange and multi-strange baryons in proton–proton (p+p), proton–lead (p+Pb), and lead–lead (Pb+Pb) collisions at Large Hadron Collider (LHC) energies

Bayesian estimation of the specific shear and bulk viscosity of quark–gluon plasma

Ultrarelativistic collisions of heavy atomic nuclei produce an extremely hot and dense phase of matter, known as quark–gluon plasma (QGP), which behaves like a near-perfect fluid with the smallest

Quark-Gluon Plasma

Meson formation and radiation at the surface of quark-gluon plasma are studied by making use of the chromoelectric flux tube model. The effect of the surface meson radiation on the hydroexpansion of
