论文摘要
LHC关于低和高横向动量的椭圆流$ v_2 $ p_t $ p_t $的LHC数据来自pb+pb碰撞，以每个核子对$ \ sqrt {s_ {s_ {nn}} = 5.02 $ tev分析了hydjet+++++++模型的框架。该模型包括柔软的硬组件，可以描述低和高横向动量的区域。 $ v_2 $ value在不同$ p_t $区域中的起源是在不同的中心进行的。结果表明，在低和高$ p_t $在外围铅铅碰撞中，实验观察到的相关性是由于喷气机中粒子的相关性。
LHC data on the correlations of the elliptic flow $v_2$ of particles at low and high transverse momenta $p_T$ from Pb+Pb collisions at center-of-mass energy per nucleon pair $\sqrt{s_{NN}} = 5.02$ TeV are analyzed in the framework of the HYDJET++ model. This model includes soft and hard components which allows to describe the region of both low and high transverse momenta. The origin of $v_2$ values in different $p_T$ regions is investigated at different centralities. It is shown that the experimentally observed correlations between $v_2$ at low and high $p_T$ in peripheral lead-lead collisions is due to correlation of particles in jets.
