摘要:

重离子碰撞中带电粒子的方位各向异性是研究早期夸克-胶子等离子体演化的重要探针。本文在HYDJET++ Monte-Carlo模型框架下分析了5.5TeV能量下不同强子种类的Pb+Pb碰撞中的椭圆流斑图。研究了共振衰减对颗粒流动的影响。在LHC条件下比较了椭圆流重建的不同方法。

英文摘要:

The azimuthal anisotropy of charged particles in heavy ion collisions is an important probe of quark-gluon plasma evolution at early stages. In the present paper the elliptic flow pattern in Pb+Pb collisions at sqrt{s}=5.5 TeV is analyzed for different hadron species in the frameworks of HYDJET++ Monte-Carlo model. The influence of resonance decays on particle flow is investigated. The different methods of elliptic flow reconstruction are compared under LHC conditions.
