超对称Yang-Mills理论中Nicolai映射的构造方法

Construction method for the Nicolai map in supersymmetric Yang-Mills theories

Olaf Lechtenfeld, Maximilian Rupprecht

摘要:

最近,人们发现了Nicolai映射用一个耦合流泛函微分算子表示的一个普适公式,并在离壳实现超对称的Yang-Mills理论中给出了该算子的全微扰展开式.鉴于这种扩展,我们开发了一个简单的方法来计算明确的尼古拉映射的任何顺序的规范耦合。我们的工作将以前已知的构造方法从朗道规范扩展到任意规范,从规范超曲面扩展到全规范场位形空间。作为一个例子,我们给出了轴向规范中的二阶映射。

英文摘要:

Recently, a universal formula for the Nicolai map in terms of a coupling flow functional differential operator was found. We present the full perturbative expansion of this operator in Yang-Mills theories where supersymmetry is realized off-shell. Given this expansion, we develop a straightforward method to compute the explicit Nicolai map to any order in the gauge coupling. Our work extends the previously known construction method from the Landau gauge to arbitrary gauges and from the gauge hypersurface to the full gauge-field configuration space. As an example, we present the map in the axial gauge to the second order.
