探索具有波动的QCD phase diagram

Exploring the QCD phase diagram with fluctuations

Volker Koch, Volodymyr Vovchenko

摘要:

本文报道了重离子碰撞中逐事件涨落理论描述的最新进展。具体来说,我们讨论了一种新的Cooper-Frye粒子化程序--子系综采样器--该程序旨在将全局守恒定律、热涂抹和共振衰变对各种快度接受度中波动测量的影响纳入其中。首先介绍了该方法在LHC能区重离子碰撞中的应用,并概述了分析RHIC束流能量扫描涨落的进一步必要步骤。

英文摘要:

We report on recent progress concerning theoretical description of event-by-event fluctuations in heavy-ion collisions. Specifically we discuss a new Cooper-Frye particlization routine -- the subensemble sampler -- which is designed to incorporate effects of global conservation laws, thermal smearing and resonance decays on fluctuation measurements in various rapidity acceptances. First applications of the method to heavy-ion collisions at the LHC energies are presented and further necessary steps to analyze fluctuations from RHIC beam energy scan are outlined.
