摘要

我们报告了关于重离子碰撞中逐个事件波动的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——亚系综采样器——它被设计成结合全局守恒定律、热涂布和共振衰减对各种快速接受的波动测量的影响。首先介绍了该方法在LHC能量重离子碰撞中的应用，并概述了进一步分析RHIC束流能量扫描波动的必要步骤。

Exploring the QCD Phase Diagram with Fluctuations

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.
