LHC和BES时代QGP的波动流体动力学

Fluctuating fluid dynamics for the QGP in the LHC and BES era

Marcus Bluhm, Marlene Nahrgang, Thomas Schaefer, Steffen A. Bass

摘要:

在高精度测定QGP性质的时代,将流体动力学涨落完全纳入我们的模型已变得至关重要,特别是在描述小系统的动力学或接近约束QCD临界点时。在这次演讲中,我们将讨论这些波动传播的一些影响。对于大型强子对撞机物理,我们专注于能量动量张量的波动,而在扩散净重子密度的波动的影响进行了研究,以提高我们的知识正在寻找在当前和未来的BES计划的临界波动的形成。

英文摘要:

In an era of high-precision determinations of QGP properties a full incorporation of fluid dynamical fluctuations into our models has become crucial, in particular, when describing the dynamics of small systems or near the conjectured QCD critical point. In this talk we discuss some effects of the propagation of these fluctuations. For LHC physics we focus on fluctuations in the energy-momentum tensor, while the impact of fluctuations in the diffusive net-baryon density is studied to improve our knowledge on the formation of critical fluctuations being searched in current and future BES programs.
