强子到夸克胶子相变中的非广延统计效应

Nonextensive statistical effects in the hadron to quark-gluon phase transition

A. Lavagno, D. Pigato, P. Quarati

摘要:

本文在非广延统计力学框架下研究了有限温度和重子密度下强子物质和夸克-胶子等离子体的相对论性状态方程,其量子分布服从幂律分布。通过要求重子数和电荷分数整体守恒的吉布斯条件,研究了从强子物质到夸克-胶子等离子体的相变。我们发现,非广泛的统计效应发挥了至关重要的作用,在状态方程和混合相的形成也从标准的玻尔兹曼-吉布斯统计的小偏差。

英文摘要:

We investigate the relativistic equation of state of hadronic matter and quark-gluon plasma at finite temperature and baryon density in the framework of the nonextensive statistical mechanics, characterized by power-law quantum distributions. We study the phase transition from hadronic matter to quark-gluon plasma by requiring the Gibbs conditions on the global conservation of baryon number and electric charge fraction. We show that nonextensive statistical effects play a crucial role in the equation of state and in the formation of mixed phase also for small deviations from the standard Boltzmann-Gibbs statistics.
