论文摘要

我们通过Jetscape框架中的夸克 - 杜伦等离子体提出了一个多阶段模型。 Jetscape中的多阶段方法提供了对虚拟性射流淋浴中不同阶段的统一描述。我们使用调谐参数证明了对领先的强子和集成的Jet可观测值以及JET $ V_N $的同时描述。基于弱耦合的后坐机处方实现对喷射淬火的中等响应。我们还探索了等离子体内部射流能量损失的锥度大小依赖性。

We present a multi-stage model for jet evolution through a quark-gluon plasma within the JETSCAPE framework. The multi-stage approach in JETSCAPE provides a unified description of distinct phases in jet shower contingent on the virtuality. We demonstrate a simultaneous description of leading hadron and integrated jet observables as well as jet $v_n$ using tuned parameters. Medium response to the jet quenching is implemented based on a weakly-coupled recoil prescription. We also explore the cone-size dependence of jet energy loss inside the plasma.
