胶子等离子体的磁分量及其粘滞性

Magnetic component of gluon plasma and its viscosity

M. N. Chernodub, H. Verschelde, V. I. Zakharov

摘要:

我们讨论了胶子等离子体的磁自由度在其粘性中的作用。主要的假设是磁分量和等离子体其余部分的运动可以被认为是独立的。用三维(欧几里德)场论描述了去精细相的磁分量。理论的参数可以从晶格数据中唯象地估计。不排除磁性成分是超流体。

英文摘要:

We discuss the role of the magnetic degrees of freedom of the gluon plasma in its viscosity. The main assumption is that motions of the magnetic component and of the rest of the plasma can be considered as independent. The magnetic component in the deconfined phase is described by a three-dimensional (Euclidean) field theory. The parameters of the theory can be estimated phenomenologically, from the lattice data. It is not ruled out that the magnetic component is superfluid.
