标题： Generalization of radiative jet energy loss to non-zero magnetic mass

摘要： 可靠的喷注淬火预测在超相对论重离子碰撞中需要准确计算辐射能量损失。 为了达到这个目标，最近开发了一种在现实有限大小动态QCD介质中的能量损失形式。 虽然这种形式假设磁质量为零——这与一环微扰计算一致——但不同的非微扰方法报告在RHIC和LHC处存在非零磁质量。 我们在这里将能量损失推广，以一致地包括存在非零磁屏蔽的可能性。 我们还展示了有限磁质量的包含如何改变能量损失结果。 我们的分析表明磁质量与电质量比值存在基本约束。 显示英文摘要

摘要： Reliable predictions for jet quenching in ultra-relativistic heavy ion collisions require accurate computation of radiative energy loss. With this goal, an energy loss formalism in a realistic finite size dynamical QCD medium was recently developed. While this formalism assumes zero magnetic mass - in accordance with the one-loop perturbative calculations - different non-perturbative approaches report a non-zero magnetic mass at RHIC and LHC. We here generalize the energy loss to consistently include a possibility for existence of non-zero magnetic screening. We also present how the inclusion of finite magnetic mass changes the energy loss results. Our analysis indicates a fundamental constraint on magnetic to electric mass ratio.
