标题： Bose-Einstein correlations in thermal field theory

摘要： 双粒子关联函数对于从局部热源（“热点”的“辉光”）发射的玻色子进行计算。 与现有工作不同，考虑了粒子分布函数梯度的一阶非平衡效应。 玻色子的能谱宽度被证明是一个重要量：如果它太小，它们就不会局部平衡，因此会显著增加测量的相关半径。 谨以此文纪念欧内斯特·维格纳和植田宏明。 显示英文摘要

摘要： Two-particle correlation functions are calculated for bosons emitted from a localized thermal source (the ``glow'' of a ``hot spot''). In contrast to existing work, non-equilibrium effects up to first order in gradients of the particle distribution function are taken into account. The spectral width of the bosons is shown to be an important quantity: If it is too small, they do not equilibrate locally and therefore strongly increase the measured correlation radius.
