手征$SU(N)$规范理论中的动力学和对称性

Dynamics and symmetries in chiral $SU(N)$ gauge theories

Stefano Bolognesi, Kenichi Konishi

摘要:

本文研究了四维空间中各种手征规范理论的动力学和对称性实现,推广了M. Shifman和本文作者,依靠标准的t Hooft异常匹配条件和其他一些一般的想法。这些要求是如此强烈,系统的动态受到严重约束。颜色-味道或颜色-味道-味道锁定,动态阿贝尔化,以及这些的组合,是强大的想法,往往导致异常匹配条件的解决方案。此外,还提出了一个关于手征规范理论中对称性破缺的质量体系的产生的猜想,这在类矢量规范理论如QCD中是没有的。

英文摘要:

Dynamics and symmetry realization in various chiral gauge theories in four dimensions are investigated, generalizing a recent work by M. Shifman and the present authors, by relying on the standard 't Hooft anomaly matching conditions and on some other general ideas. These requirements are so strong that the dynamics of the systems are severely constrained. Color-flavor or color-flavor-flavor locking, dynamical Abelianization, and combinations of these, are powerful ideas which often leads to solutions of the anomaly matching conditions. Moreover, a conjecture is made on generation of a mass hierarchy associated with symmetry breaking in chiral gauge theories, which has no analogues in vector-like gauge theories such as QCD.
