热强子气体电导率的动力学研究

Electric Conductivity of a hot hadron gas from a kinetic approach

Moritz Greif, Carsten Greiner, Gabriel S. Denicol

摘要:

本文从玻尔兹曼方程出发,计算了具有各向同性截面的相对论粒子气体的电导率。我们的分析仅限于弹性碰撞。我们显示了与以前发表的无质量夸克-胶子等离子体的数值结果完全一致,并给出了相互作用的强子气体的电导率的结果,采用现实的共振截面。这些在相对论性重离子碰撞中产生的热强子气体的电导率的结果具有丰富的唯象性和理论意义,并且可以与,例如,格点量子场论计算。

英文摘要:

We calculate the electric conductivity of a gas of relativistic particles with isotropic cross sections using the Boltzmann equation as the starting point. Our analyses is restricted to elastic collisions. We show the perfect agreement with previously published numerical results for a massless quark- gluon plasma, and give results for the electric conductivity of an interacting hadron gas, employing realistic resonance cross sections. These results for the electric conductivity of a hot hadron gas, as created in (ultra-)relativistic heavy-ion collisions, are of rich phenomenological as well as theoretical interest and can be compared to, e.g., lattice quantum field theory calculations.
