摘要:

我们系统地比较了一个事件一个事件的重离子碰撞模型从大型强子对撞机的数据。使用一般的贝叶斯方法,我们探测多个模型参数,包括基本夸克-胶子等离子体体的特性,如特定的剪切粘度$η/s$,校准模型,以最佳地再现实验数据,并同时提取所有参数的定量约束。该方法具有通用性,易于扩展到其他数据和碰撞模型。

英文摘要:

We systematically compare an event-by-event heavy-ion collision model to data from the Large Hadron Collider. Using a general Bayesian method, we probe multiple model parameters including fundamental quark-gluon plasma properties such as the specific shear viscosity $η/s$, calibrate the model to optimally reproduce experimental data, and extract quantitative constraints for all parameters simultaneously. The method is universal and easily extensible to other data and collision models.
