AI总结:

本文应用BRST算符于复规范场论破缺相,通过上同调方法将凝聚态刻画为物理可观测量,为禁闭机制提供形式化描述。

摘要:

不久前,我们引入了一种实现禁闭的途径,即粒子激发可源于不具有物理渐近态的场凝聚。我们设想这一机制存在于复规范场理论的不对称真空相中。最近,我们展示了如何为一般自发破缺场论的破缺相定义BRST算符。本文旨在将这些最新概念应用于先前的复场论,以对这些凝聚态进行上同调刻画,将其视为该理论在破缺相中的真实物理可观测量。

英文摘要:

Some time ago we have introduced a route to provide confinement in the sense that particle excitations would appear from condensates of fields that do not have physical asymptotic states. We envisaged this mechanism in an asymmetric vacuum phase of a complex gauge field theory. More recently, we showed how to define a BRST operator to the broken phase of a generic spontaneous broken field theory. Our intention here is to apply these late concepts to the previous complex field theory in order to give a cohomological characterization of those condensed states as actual physical observables of this theory in its broken phase.
