5+1维非阿贝尔自对偶规范理论

A Non-Abelian Self-Dual Gauge Theory in 5+1 Dimensions

Pei-Ming Ho, Kuo-Wei Huang, Yutaka Matsuo

摘要:

我们构造了一个6维手征2-形式(自对偶规范场)的非阿贝尔规范理论,其空间方向在半径为R的圆上紧化。它具有以下两个属性。(1)当R较小时,它在5维空间中退化为Yang-Mills理论。(2)当规范群是阿贝尔群时,它等价于阿贝尔手征2-形式的洛伦兹不变量理论。通过引入紧化维数的非定域性,避免了以前禁止手征2-形式规范理论的非阿贝尔变形的不可行定理。

英文摘要:

We construct a non-Abelian gauge theory of chiral 2-forms (self-dual gauge fields) in 6 dimensions with a spatial direction compactified on a circle of radius R. It has the following two properties. (1) It reduces to the Yang-Mills theory in 5 dimensions for small R. (2) It is equivalent to the Lorentz-invariant theory of Abelian chiral 2-forms when the gauge group is Abelian. Previous no-go theorems prohibiting non-Abelian deformations of the chiral 2-form gauge theory are circumvented by introducing nonlocality along the compactified dimension.
