作为混合相位信号的热力学异常区
Thermodynamically Anomalous Regions As A Mixed Phase Signal
摘要：
使用最先进的模型的强子共振气体，我们揭示，在化学冻结，显着的不规则性，如突然变化的有效自由度和高原的碰撞能量依赖的熵每重子，每重子的总π介子数，和热π介子数每重子在实验室能量6.9-11.6 AGeV。在广义激波振荡模型的基础上，我们证明了这些平台为混合相在其与夸克-胶子等离子体（QGP）边界处的热力学反常性质提供了证据。提出并证明了QGP形成的新信号。
英文摘要：
Using the most advanced model of the hadron resonance gas we reveal, at chemical freeze-out, remarkable irregularities such as an abrupt change of the effective number of degrees of freedom and plateaus in the collision-energy dependence of the entropy per baryon, total pion number per baryon, and thermal pion number per baryon at laboratory energies 6.9-11.6 AGeV. On the basis of the generalized shock adiabat model we show that these plateaus give evidence for the thermodynamic anomalous properties of the mixed phase at its boundary to the quark-gluon plasma (QGP). A new signal for QGP formation is suggested and justified.
