随着LHC的运行，Pb-Pb碰撞将是进一步研究量子色动力学(QCD)相变及新的物质形态的理想实验. 由于LHC中Pb-Pb的质心系能量将达到5.5ATeV，因此可以预计，LHC将会有更多新物理现象. 其中，QCD理论所预言的夸克物质及其性质将是一个重要的研究课题之一. 本项目研究夸克物质的演化及其在非平衡相变中的可观测效应. 将重点研究 LHC上的可观测信号,如：光子、双轻子、矢量介子、奇异粒子、重夸克物理等信息。研究它们对相变临界点的影响. 这些问题的研究对于进一步揭示夸克物质的性质，探索强关联物理系统，在非平衡相变中的规律具有重要的物理意义.

Pb-Pb collisions may be the ideal experiments for the reseaches on quantum chromodynamics(QCD) phase transition and new state of matter with the running of the Large Hadron Collider(LHC). As the centre of mass energy is 5.5ATeV , one can expercts that there may be more new phenomena could be observed. Among the new phinomena the quark matter predicted by the theroy of QCD is one of the most important problems. In the program we study the evolution of quark matter and its obersverale efectios in nonequivalent phase transition. We are focusing on the observable signals at LHC such as: photons,dileptons,vector mesons, strangness,heavy quark physics et al..Which are significant in search of the properties of QGP matter and strong correlative system in nonequilibrium phase transitions.
