论文摘要
使用基于彩色玻璃冷凝物框架和稀释浓密分解的模型，我们系统地研究了质核核糖碰撞中浓风味梅森和光参考粒子之间的方位角角相关性。获得的第二个谐波系数（也称为椭圆流），$ j/ψ$和$ d^0 $与LHC的最新实验数据一致。我们还提供了$υ$和$ b $介入的椭圆流的预测，可以在不久的将来在LHC进行测量。这项工作可以阐明集体现象在小型系统碰撞中的物理起源。
Using a model based on the Color Glass Condensate framework and the dilute-dense factorization, we systematically study the azimuthal angular correlations between a heavy flavor meson and a light reference particle in proton-nucleus collisions. The obtained second harmonic coefficients (also known as the elliptic flows) for $J/ψ$ and $D^0$ agree with recent experimental data from the LHC. We also provide predictions for the elliptic flows of $Υ$ and $B$ meson, which can be measured in the near future at the LHC. This work can shed light on the physics origin of the collectivity phenomenon in the collisions of small systems.
