超对称Yang-Mills理论的微扰线性化

Perturbative linearization of supersymmetric Yang-Mills theory

Sudarshan Ananth, Olaf Lechtenfeld, Hannes Malcha, Hermann Nicolai, Chetan Pandey, Saurabh Pant

摘要:

超对称规范理论的特征在于存在玻色子场的变换(尼古拉映射),使得变换的雅可比行列式等于马修斯-萨拉姆-塞勒和法迪耶夫-波波夫行列式的乘积。这种转换已被计算到耦合常数的二阶。在本文中,我们将这个结果(和框架本身)推广到三阶的耦合常数。一个图解的方法,在树图,旨在将此映射扩展到任意顺序,概述。这种形式主义完全绕过了反对易变量的使用,以及关于这些理论的离壳公式(不)存在的问题。因此,它提供了一个新的视角超对称规范理论,特别是无处不在的$\mathcal N{=}\,4$理论。

英文摘要:

Supersymmetric gauge theories are characterized by the existence of a transformation of the bosonic fields (Nicolai map) such that the Jacobi determinant of the transformation equals the product of the Matthews-Salam-Seiler and Faddeev-Popov determinants. This transformation had been worked out to second order in the coupling constant. In this paper, we extend this result (and the framework itself) to third order in the coupling constant. A diagrammatic approach in terms of tree diagrams, aiming to extend this map to arbitrary orders, is outlined. This formalism bypasses entirely the use of anti-commuting variables, as well as issues concerning the (non-)existence of off-shell formulations for these theories. It thus offers a fresh perspective on supersymmetric gauge theories and, in particular, the ubiquitous $\mathcal N{=}\,4$ theory.
