论文摘要

我们研究了Jetscape框架中夸克 - 杜伦等离子体中喷射进化的媒介反应。在框架中的多阶段喷射能量损坏模型中，在弱耦合描述中的后坐力部分响应实现。作为进一步的扩展，对流体动力学描述进行了重新排列，以包括基于强耦合图片的中等射流运输。对于与JET能量减速模型的界面流体动力学，流体动力源项是通过使用相对论扩散方程的因果制剂来建模的。通过具有弱耦合后坐力的逼真的模拟来研究射流形状和碎片函数。我们还证明了由流体动力反应引起的培养基的修饰。

We study the medium response to jet evolution in the quark-gluon plasma within the JETSCAPE framework. Recoil partons' medium response in the weakly coupled description is implemented in the multi-stage jet energy-loss model in the framework. As a further extension, the hydrodynamic description is rearranged to include in-medium jet transport based on a strong-coupling picture. To interface hydrodynamics with jet energy-loss models, the hydrodynamic source term is modeled by a causal formulation employing the relativistic diffusion equation. The jet shape and fragmentation function are studied via realistic simulations with weakly coupled recoils. We also demonstrate modifications in the medium caused by the hydrodynamic response.
