Initial state and thermalisation dynamics in heavy-ion collisions (A01)

该项目的中心目标是从头计算重离子碰撞早期阶段夸克-胶子物质的时空演化，并设计合适的观测值来实验解结不同阶段。随着新的光子分析方法和现象学模型的发展，在非常低的横向动量（低于1 GeV/c）下，与QCD动力学和光子产生相关的计算是一个重要方面。进一步的目标是研究平衡前的高阶相关性，包括研究在低横向动量下测量光子波动的鲁棒方法。此外，还将对重子数和奇异度等守恒量的涨落进行理论和实验研究。这包括用于测量6阶累积量的分析方法的发展。

The central goal of this project is the ab initio calculation of the space-time evolution of the quark-gluon matter at early stages of a heavy-ion collision and to devise suitable observables to disentangle different stages experimentally. An important aspect are calculations related to QCD dynamics and photon production at very low transverse momenta (below 1 GeV/c) accompanied by the development of novel photon analysis methods and phenomenological models. A further goal is the study of pre-equilibrium higher-order correlations including investigations into robust methods for measuring photon fluctuations at low transverse momenta. Moreover, fluctuations of conserved quantities like baryon number and strangeness will be studied theoretically and experimentally. This includes the development of analysis methods for measuring cumulants up to the 6th order.
