摘要
JETSCAPE 合作组报告了在夸克-胶子等离子体（QGP）中喷注输运系数的新确定，使用了在 RHIC 与 LHC 上测量的重建喷注与强子数据。JETSCAPE 框架包含 QGP 动力学演化的详细建模、介质内喷注演化与介质响应的多阶段理论方法，以及用于模型计算与数据定量比较的贝叶斯推断。多阶段框架结合多个模型以覆盖介质内部部分子簇射演化尺度的宽广范围，并根据部分子当前虚度或能量动态选择模型。我们将讨论多尺度建模的物理，随后给出结合它的新贝叶斯分析。该分析扩展了最近发表的仅基于含强子抑制数据的 JETSCAPE 喷注输运参数 确定，纳入了重建喷注的淬火测量。我们探索了喷注输运系数对 QGP 温度及喷注能量和虚度的函数依赖，并报告了当前喷注淬火建模在宽泛运动学与 范围内与强子和重建喷注数据的一致性与张力。该分析是全面分析喷注淬火现象学及其对 QGP 性质约束这一计划的下一步。
