流体力学中的重味流动

The flow of heavy flavor in hydrodynamics

Taesoo Song, Woosung Park, Su Houng Lee

摘要:

在相对论重离子碰撞中,假设$c\bar{c}$对的数目守恒,通过引入$c\bar{c}$对的电荷,计算了2+1理想流体力学中的粲流.发现在RHIC条件下,粲夸克的平均径向流速比体物质的平均径向流速小10 $\sim$ 15%,重味电子的$v_2$测量值在$p_T^e=$ 1.5GeV/c以下重现.将相同的流程应用于再生的$J/ψ$并讨论其$v_2$。

英文摘要:

The flow of charm is calculated in 2+1 ideal hydrodynamics by introducing the charge of $c\bar{c}$ pair assuming that the number of $c\bar{c}$ pairs is conserved in relativistic heavy-ion collisions. It is found that the mean radial flow velocity of charm quarks is smaller than that of bulk matter by 10$\sim$15 \% and the measured $v_2$ of heavy-flavor electrons is reproduced up to $p_T^e=$ 1.5 GeV/c in Au+Au collision at RHIC. The same flow is applied to regenerated $J/ψ$ and its $v_2$ is discussed.
