标题： (Non-)Aligned gauges and global gauge symmetry breaking

摘要： 规范对称性破缺（全局）的概念在物理学的许多领域中扮演着重要角色。 由于相应的对称性是一种规范对称性，因此其破缺实际上是规范相关的。 因此，可以设计规范来尽可能好地恢复这种对称性。 这里将详细讨论这类规范构造，并通过格点规范理论加以说明。 它们将在希格斯效应、高密色超导体以及BRST对称性的案例中进行讨论。 显示英文摘要

摘要： The concept of (global) gauge symmetry breaking plays an important role in many areas of physics. Since the corresponding symmetry is a gauge symmetry, its breaking is actually gauge-dependent. Thus, it is possible to design gauges which restore the symmetry as good as possible. Such gauge constructions will be detailed here, illustrated with the use of lattice gauge theory. Their use will be discussed for the cases of the Higgs effect, high-baryon density color superconductors, and BRST symmetry.
