演化系统中n点电荷关联的计算
Calculating n-Point Charge Correlations in Evolving Systems
摘要：
在动力学系统中，电荷极化率和局部电荷相关性随时间而变化。这些变化是伴随着非本地的相关性扩散随时间的推移，并受到本地电荷守恒。假设局部特征的相关性，这对于气体将是在同一个粒子内的电荷的相关性，是平衡的，一个图解形式主义，用于计算相关的非局部相关性的演变。这些提供了任意$n$在不同位置的$n$密度算子的相关性。这些技术是着眼于相对论性重离子碰撞而开发的，可以解释由上、下和奇怪电荷索引的相关性。理解这种相关性的演变是至关重要的，如果一个是解释相对论重离子对撞机的电荷波动的测量。
英文摘要：
In dynamic systems, charge susceptibilities and local charge correlations change with time. These changes are accompanied by non-local correlations which spread diffusively with time and are constrained by local charge conservation. Assuming the local features of the correlation, which for a gas would be the correlation of charges within the same particle, are equilibrated, a diagrammatic formalism is presented for calculating the evolution of the associated non-local correlations. These provide correlations of $n$ density operators at different positions for arbitrary $n$. The techniques were developed with an eye towards relativistic heavy-ion collisions, and can account for correlations indexed by up, down and strange charges. Understanding the evolution of such correlations is crucial if one is to interpret measurements of charge fluctuations from the Relativistic Heavy-Ion Collider.
