不满足高斯定律的Faddeev-Niemi解

A Faddeev-Niemi Solution that Does Not Satisfy Gauss' Law

Jarah Evslin, Simone Giacomelli

摘要:

Faddeev和Niemi提出了一个SU(2)Yang-Mills理论的重新表述,它是一个具有8个离壳自由度的U(1)规范理论。我们提出了一个解决方案,Faddeev和Niemi的制定,不解决SU(2)杨米尔斯高斯约束。这表明,所提出的重新表述是不等价的杨米尔斯,而是描述杨米尔斯耦合到一个特定的选择的外部电荷。

英文摘要:

Faddeev and Niemi have proposed a reformulation of SU(2) Yang-Mills theory in terms of a U(1) gauge theory with 8 off-shell degrees of freedom. We present a solution to Faddeev and Niemi's formulation which does not solve the SU(2) Yang-Mills Gauss constraints. This demonstrates that the proposed reformulation is inequivalent to Yang-Mills, but instead describes Yang-Mills coupled to a particular choice of external charge.
