摘要:

我们进行了全球贝叶斯分析的现代事件的重离子碰撞模型和大型强子对撞机数据在$\sqrt s$ = 2.76和5.02 TeV。校准后,该模型同时描述多重性,横向动量,并在两个光束能量的流量数据。我们报告的初始状态熵沉积和QGP输运系数的标度的新的限制,包括温度依赖的剪切粘度$(η/s)(T)$的定量估计。

英文摘要:

We perform a global Bayesian analysis of a modern event-by-event heavy-ion collision model and LHC data at $\sqrt s$ = 2.76 and 5.02 TeV. After calibration, the model simultaneously describes multiplicity, transverse momentum, and flow data at both beam energies. We report new constraints on the scaling of initial-state entropy deposition and QGP transport coefficients, including a quantitative estimate of the temperature-dependent shear viscosity $(η/s)(T)$.
