在RHIC是否观察到PDKEEPAAA临界点?

Has the QCD critical point been observed at RHIC?

N. G. Antoniou, N. Davis, F. K. Diakonos

摘要:

在相图中寻找QCD临界点的实验是至关重要的。在最近的一份出版物中,声称RHIC的测量不仅导致临界点($μ_{cep}=95$ MeV,$T_{cep}=165$ MeV)的位置,而且还通过提取临界指数($γ=1.2$,$ν=0.66$)的值来验证其普适性类($3d$ Ising系统)。我们认为,这种说法是基于一个错误的处理标度关系的临界点附近。因此,测量的正确解释不能与QCD临界点联系起来。

英文摘要:

The experimental search for the location of the QCD critical point in the phase diagram is of primary importance. In a recent publication it is claimed that measurements at RHIC lead not only to the location of the critical point ($μ_{cep}=95$ MeV, $T_{cep}=165$ MeV) but also to the verification of its universality class ($3d$ Ising system) by extracting the values of the critical exponents ($γ=1.2$, $ν=0.66$). We argue that this claim is based on an erroneous treatment of scaling relations near the critical point. As a result, the correct interpretation of the measurements cannot be linked to the QCD critical point.
