摘要:

我们提出了一个贝叶斯分析一类新的现实模型的两相状态方程(EoS)的混合星,并证明了一对高质量的双星的观察将有足够的鉴别力,有利于混合EoS与一个强大的第一阶相变替代EoS。这样的测量将为QCD相图中存在临界端点提供证据。

英文摘要:

We present a Bayesian analysis for a new class of realistic models of two-phase equations of state (EoS) for hybrid stars and demonstrate that the observation of a pair of high-mass twin stars would have a sufficient discriminating power to favor hybrid EoS with a strong first order phase transition over alternative EoS. Such a measurement would provide evidence for the existence of a critical endpoint in the QCD phase diagram.
