论文摘要

使用Jetscape研究了浓风味与相对论重型离子碰撞中的夸克 - 格鲁恩等离子体（QGP）的相互作用，这是一种公开可用的软件包，该软件包包含蒙特卡洛事件生成器的框架。 jetscape中重夸克的多阶段（和多模型）演变提供了对QGP内部浓烈风味淬火的凝聚力描述。随着Parton淋浴的发展，一旦达到其有效性区域，模型就会变得活跃。在逼真的QGP介质中探索了重量降温损失模型的两种组合，并使用调谐的参数来描述{\ it Light-Favor} partononic-Energy-aloss。

The interaction of heavy flavor with the quark-gluon plasma (QGP) in relativistic heavy-ion collisions is studied using JETSCAPE, a publicly available software package containing a framework for Monte Carlo event generators. Multi-stage (and multi-model) evolution of heavy quarks within JETSCAPE provides a cohesive description of heavy flavor quenching inside the QGP. As the parton shower develops, a model becomes active as soon as its kinematic region of validity is reached. Two combinations of heavy-flavor energy-loss models are explored within a realistic QGP medium, using parameters which were tuned to describe {\it light-flavor} partonic energy-loss.
