论文摘要

我们使用高效的Monte Carlo波函数函数方法在强耦合的夸克 - 胶状等离子体中求解了cOULOMBIC重型夸克 - 敌对对的lindblad方程。 lindblad方程已在PNRQCD的框架中得出,并完全解释了系统的量子和非亚洲性质。通过3+1D耗散性流体动力学代码,实际实现了血浆的流体动力学。我们计算底部核修饰因子,并与最新的LHC数据进行比较。该计算不依赖任何自由参数,因为它取决于在晶格QCD中独立评估的两个传输系数。我们的最终结果包括激发态的延迟馈送,与LHC 5.02 TEV PBPB碰撞的可用数据一致。

We solve the Lindblad equation describing the Brownian motion of a Coulombic heavy quark-antiquark pair in a strongly coupled quark-gluon plasma using the highly efficient Monte Carlo wave-function method. The Lindblad equation has been derived in the framework of pNRQCD and fully accounts for the quantum and non-Abelian nature of the system. The hydrodynamics of the plasma is realistically implemented through a 3+1D dissipative hydrodynamics code. We compute the bottomonium nuclear modification factor and compare with the most recent LHC data. The computation does not rely on any free parameter, as it depends on two transport coefficients that have been evaluated independently in lattice QCD. Our final results, which include late-time feed down of excited states, agree well with the available data from LHC 5.02 TeV PbPb collisions.
