夸克-胶子等离子体的贝叶斯量化:改进的设计和闭合验证
Bayesian quantification of the Quark-Gluon Plasma: Improved design and closure demonstration
摘要:
我们提出了一个示范的设计抽样和封闭的第一个全面的贝叶斯模型的重离子测量与IP-Escomma的初始条件,其中我们结合了国家的最先进的流体力学(MUSIC),粒子化(iS 3D),和运输(SMASH)的数据比较。我们进一步介绍了一个系统的改进方法,采样设计点具有更好的投影性能,探索参数空间的模型在重离子碰撞的第一次。
英文摘要:
We present a demonstration of the design sampling and closure for the first comprehensive Bayesian model-to-data comparison of heavy-ion measurements with IP-Glasma initial conditions, in which we combine with state-of-the-art hydrodynamics (MUSIC), particlization (iS3D), and transport (SMASH). We further introduce a systematically-improvable method of sampling design points with better projection properties to explore the parameter space of the model for the first time in heavy-ion collisions.
