The discovery of gluon-dominant system in heavy ion collisions ---- the large elliptic flow of direct photons

Abstract

The discussion of the large elliptic flow of direct photons in Quark Matter 2014 has been reviewed. Then based on previous technique work, the physics meaning related to the large elliptic flow of direct photons is invetigated in this paper.
