论文摘要
Gribov量化是一种改善Yang-Mills理论红外动力学的方法。我们研究了血浆的热力学和运输特性，该等离子体由Gribov处方改善传播剂的胶子组成。我们首先使用仪表不变的Gribov分散性关系来构建Gribov血浆的热力学。当分散关系中的Gribov参数取决于温度时，人们期望对Boltzmann方程进行平均场校正。我们为Gribov等离子体制定协变量理论，并确定Boltzmann方程中的平均场贡献。这导致了类似框架的准粒子，并对压力和能量密度进行袋校正，并模仿限制。 Gribov参数和BAG压力的温度依赖性是通过与胶子系统的晶格结果匹配来固定的。最后，我们计算传输系数的温度依赖性，即散装和剪切粘度。
Gribov quantization is a method to improve the infrared dynamics of Yang-Mills theory. We study the thermodynamics and transport properties of a plasma consisting of gluons whose propagator is improved by the Gribov prescription. We first construct thermodynamics of Gribov plasma using the gauge invariant Gribov dispersion relation for interacting gluons. When the Gribov parameter in the dispersion relation is temperature dependent, one expects a mean field correction to the Boltzmann equation. We formulate covariant kinetic theory for the Gribov plasma and determine the mean-field contribution in the Boltzmann equation. This leads to a quasiparticle like framework with a bag correction to pressure and energy density which mimics confinement. The temperature dependence of the Gribov parameter and bag pressure is fixed by matching with lattice results for a system of gluons. Finally we calculate the temperature dependence of the transport coefficients, i.e., bulk and shear viscosities.
