摘要

在本文中，我们分析了相对于强均匀平均磁场背景的随机空间磁波动对热化夸克-胶子等离子体相中光子和双轻子发射过程产率的影响。这种随机波动模拟了参与非中心重离子碰撞的原子核几乎随机初始条件的影响，这些碰撞是背景磁场的来源。我们的理论结果预测了在这种情况下，由于随机磁噪声对光子和双轻子产生率的角分布的显著各向异性效应。2025年由美国物理学会出版

Anisotropic photon and dilepton yield in a thermalized quark-gluon plasma under spatial magnetic fluctuations

In this article, we analyze the effects of stochastic spatial magnetic fluctuations with respect to an intense uniform average magnetic field background over the yields for photon and dilepton emission processes in a thermalized quark-gluon plasma phase. Such stochastic fluctuations model the effects of nearly random initial conditions for the nuclei participating in noncentral heavy-ion collisions, which are the sources of the background magnetic field. Our theoretical results predict significant anisotropic effects due to stochastic magnetic noise over the angular distribution for photon and dilepton production rates in this scenario.
