论文摘要
在密集的涂色玻璃冷凝物方法中，并使用Golec-Biernat-wuesthoff模型用于偶极散射幅度，我们计算了$ V_2^2 $以及$ V_2^2 $和总的多样性和平均生产粒子的平均横向动量之间的相关性。我们发现相关性通常与观察值一致。我们注意到$ v^2_2 $的值及其相关性与横向动量箱宽度的函数的急剧变化。该交叉与狭窄垃圾箱的相关性增强相关性到HBT的相关性占主导地位的相关性的变化有关。
Within the dense-dilute Color Glass Condensate approach, and using the Golec-Biernat-Wuesthoff model for the dipole scattering amplitude, we calculate $v_2^2$ as well as the correlations between $v_2^2$ and both the total multiplicity and the mean transverse momentum of produced particles. We find that the correlations are generally very small consistent with the observations. We note an interesting sharp change in the value of $v^2_2$ as well as of its correlations as a function of the width of the transverse momentum bin. This crossover is associated with the change from Bose enhancement dominance of the correlation for narrow bin to HBT dominated correlations for larger bin width.
