The goal of this project is to provide a high-order Taylor expansion of the grand partition function of QCD. In this project we will further advance the numerical tools that allow for the calculation of up to eighth-order Taylor-expansion coefficients with sufficient accuracy to provide bounds on the location of a possible critical endpoint in the QCD phase diagram. The research program includes the calculation of the Taylor-expansion coefficients and the analysis of phenomenological consequences concerning their relevance for the hydrodynamic modeling of matter created in heavy-ion collisions.

该项目的目标是提供 QCD 宏配分函数的高阶泰勒展开。在这个项目中，我们将进一步改进数值工具，以足够的精度计算高达八阶泰勒展开系数，以提供 QCD 相图中可能的临界端点位置的界限。该研究计划包括计算泰勒展开系数以及分析其与重离子碰撞中产生的物质的流体动力学模型的相关性的现象学后果。
