摘要:

在JETSCAPE框架下,我们提出了一个描述喷流在夸克-胶子等离子体中演化的多阶段模型。JETSCAPE中的多阶段方法提供了一个统一的描述,在射流簇射视虚拟的不同阶段。我们展示了一个同时描述领先的强子和综合喷流观测以及射流$v_n$使用调谐参数。介质响应射流淬火的基础上实现了弱耦合反冲处方。我们还探讨了等离子体内的射流能量损失的锥形尺寸依赖。

英文摘要:

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.
