论文摘要
我们使用开放的量子系统方法计算PNRQCD有效场理论中的底部抑制和椭圆流。对于流体动力学背景，我们使用2+1D音乐二阶粘性水动力学具有IP-Glasma初始条件，并在这些背景下实时进化底部/Antibottom量子波。我们发现，与使用平滑初始条件获得的结果相比，波动初始条件的影响很小。包括波动初始条件的影响，我们发现UPSILON（1s）集成的椭圆流为V_2 [1S] = 0.005 +/- 0.002 +/- 0.001，其第一和第二变化分别对应于统计和系统的理论不确定性。
We compute bottomonium suppression and elliptic flow within the pNRQCD effective field theory using an open quantum systems approach. For the hydrodynamical background, we use 2+1D MUSIC second-order viscous hydrodynamics with IP-Glasma initial conditions and evolve bottom/antibottom quantum wave packets in real time in these backgrounds. We find that the impact of fluctuating initial conditions is small when compared to results obtained using smooth initial conditions. Including the effect of fluctuating initial conditions, we find that the Upsilon(1S) integrated elliptic flow is v_2[1S] = 0.005 +/- 0.002 +/- 0.001, with the first and second variations corresponding to statistical and systematic theoretical uncertainties, respectively.
