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

摘要： 研究了四维各种手征规范理论的动力学及其对称性实现，推广了M. Shifman与作者最近的一项工作，依靠的是标准的't Hooft反常匹配条件以及其他一些普遍的思想。 这些要求非常强，以至于系统的动力学受到严重约束。 色味锁定、动态阿贝尔化以及它们的组合，是强有力的想法，常常能导致反常匹配条件的解。 此外，对与手征规范理论中的对称破缺相关的质量层次结构的生成提出了一项猜想，这在像QCD这样的向量规范理论中没有类似物。 显示英文摘要

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.
