色超导性的若干问题:引论

Some aspects of color superconductivity: an introduction

Qun Wang

摘要:

对弱耦合极限下的色超导性作了教学介绍。重点是基本工具的热场论必要的计算观测的颜色超导性。在Anderson-Higgs机制的基础上分析了其丰富的对称性结构和对称性破缺模式。一些技术也可以用于计算致密星中的中微子过程。作为一个例子,我们展示了如何通过计算W玻色子的极化张量来获得中子星中Urca过程的中微子发射率。我们还说明了如何自旋1色超导相产生各向异性中微子发射致密星。

英文摘要:

A pedagogical introduction to color superconductivity in the weak coupling limit is given. The focus is on the basic tools of thermal field theory necessary to compute observables of color superconductivity. The rich symmetry structure and symmetry breaking patterns are analyzed on the basis of the Anderson-Higgs mechanism. Some techniques can also be applied for computing neutrino processes in compact stars. As an example, we show how to obtain the neutrino emissivity for Urca processes in neutron stars by computing the polarization tensor of the W-boson. We also illustrate how a spin-1 color superconducting phase generates an anisotropic neutrino emissions in compact stars.
