论文摘要
无Xtentendition的统计数据引起了人们对QCD能量核碰撞中粒子光谱的描述。首先，我们通过基于强子共振气体和Parton气体模型合并Tsallis统计来构建状态方程。发现热力学条件对Tsallis分布的$ Q $参数施加限制。接下来，我们将状态方程式应用于核碰撞的相对论水动力建模。 Cooper-Frye处方始终被修改。数值证明表明，该模型可以描述横向动量范围为6-8 GEV的大型强子对撞机的带电颗粒光谱。另一方面，椭圆流表明适用性范围更窄。
Nonextensive statistics has attracted attention as a description of particle spectra in nuclear collisions at QCD energies. First, we construct the equation of state by incorporating Tsallis statistics based on the hadron resonance gas and parton gas models. Thermodynamic conditions are found to impose constraints on the $q$-parameter of Tsallis distribution. Next, we apply the equation of state to the relativistic hydrodynamic modeling of nuclear collisions. The Cooper-Frye prescription is consistently modified. Numerical demonstrations indicate that the model may describe charged particle spectra at Large Hadron Collider in the transverse momentum range up to 6-8 GeV. Elliptic flow, on the other hand, suggests a narrower range of applicability.
