论文摘要
在有限的时间路径范围内量子场理论（QFT）中，我们从狭窄的窗口中计算出从重离子碰撞的早期阶段的直接光子发射，其中不确定性关系仍然很重要，它们为生产光子的生产提供了新的机制。关于早期计算的基本差异，导致结果分歧，是我们使用夸克和光子的重新归一化QED。我们的结果是与不确定性关系一致的有限贡献。
Within the finite-time-path out-of-equilibrium quantum field theory (QFT), we calculate direct photon emission from early stages of heavy ion collisions, from a narrow window, in which uncertainty relations are still important and they provide a new mechanism for production of photons. The basic difference with respect to earlier calculations, leading to diverging results, is that we use renormalized QED of quarks and photons. Our result is a finite contribution that is consistent with uncertainty relations.
