自对偶规范场的洛伦兹协变拉格朗日量

Lorentz Covariant Lagrangians of Self-dual Gauge Fields

Wung-Hong Huang

摘要:

我们推广了PST公式化方法,找到了一种系统的方法来协变几个非协变的自对偶规范场的拉格朗日量。我们详细推导出必要的基本公式,用于证明存在的额外的局部对称性,使我们能够规范固定其中的辅助字段和非协变配方恢复。我们看到,在PST和PSST公式,描述的协变拉格朗日在6D分解的$6=1+5$和$6=3+3$分别,超局部对称性,可以表示为一个简单的线性形式的场强。然而,虽然本文在$6=2+4$的另一种分解中发现了协变拉格朗日量,但规范场的超定域对称性在场强上不能表示为简单的线性形式。我们提出了一个不去定理来证明这个特定的属性。我们还发现其他协变拉格朗日更复杂的时空分解。

英文摘要:

We extend the method of PST formulation to find a systematic way to covariantize several non-covariant Lagrangians of self-dual gauge fields. We derive in detail the necessary basic formulas which are used to prove the existence of extra local symmetry that allows us to gauge fix the auxiliary fields therein and non-covariant formulations are restored. We see that, the extra local symmetry in the PST and PSST formulations, which describe the covariant Lagrangians in the 6D decomposition of $6=1+5$ and $6=3+3$ respectively, can be expressed as a simple linear form in the field strength. However, although in this paper we have found the covariant Lagrangians in the other decomposition of $6=2+4$, the extra local symmetry of the gauge field cannot be expressed as a simple linear form in the field strength. We present a no-go theorem to prove this specific property. We also find other covariant Lagrangians with more complex decomposition of spacetime.
