论文摘要
穿越夸克 - 杜伦等离子体的充满活力的Parton通过偶尔的硬散射和频繁的相互作用而失去能量。无论这些相互作用是否接受扰动描述，都可以将软相互作用的效果分解和编码，以少量的传输系数。在这项工作中，我们提出了一个硬化分解的Parton能量损失模型，该模型结合了软相互作用的随机描述和基于速率的硬散射建模。我们引入了一个量表，以估计随机描述的有效性状态，从而可以更好地理解大小耦合时模型的适用性。我们研究了能量部分的能量和费米级级联，作为模型的应用。
An energetic parton travelling through a quark-gluon plasma loses energy via occasional hard scatterings and frequent softer interactions. Whether or not these interactions admit a perturbative description, the effect of the soft interactions can be factorized and encoded in a small number of transport coefficients. In this work, we present a hard-soft factorized parton energy loss model which combines a stochastic description of soft interactions and rate-based modelling of hard scatterings. We introduce a scale to estimate the regime of validity of the stochastic description, allowing for a better understanding of the model's applicability at small and large coupling. We study the energy and fermion-number cascade of energetic partons as an application of the model.
