Abstract

The quark number susceptibility near the QCD critical end point (CEP), the tricritical point (TCP) and the $O(4)$ critical line at finite temperature and quark chemical potential are investigated. Based on the universality argument and numerical model calculations we propose the possibility that the hidden tricritical point strongly affects the critical phenomena around the critical end-point. We make a semiquantitative study of the quark number susceptibility near CEP or TCP for several quark masses on the basis of the Cornwall-Jackiw-Tomboulis potential for QCD in the improved-ladder approximation. The results show that the susceptibility is enhanced in a wide region around the CEP, inside which the critical exponent gradually changes from that of the CEP to that of the TCP, indicating a crossover of different universality classes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
