摘要:

本文在玻恩近似下研究了N=4超杨-米尔斯理论中非手征应力张量多重态的多点超关联函数。我们推导出有效的超图费曼规则。令人惊讶的是,非手征双折射子的费曼规则是由手征双折射子的费曼规则通过时空变量的简单格拉斯曼位移得到的。我们依赖于洛伦兹谐波手征(LHC)超空间中的理论公式,该理论在双论文arXiv:1601.06803中详细阐述。在这种方法中,只有手征的一半超对称性是明显的。另一半是通过LHC超场的非线性和非局域变换实现的。然而,在玻恩水平上,只有简单的线性部分的转换是相关的。它对应于在理论的自对偶部分有效地工作。我们的方法也适用于更广泛的一类超多重峰,如所有的半BPS运营商和小西多重峰。

英文摘要:

We study the multipoint super-correlation functions of the full non-chiral stress-tensor multiplet in N=4 super-Yang-Mills theory in the Born approximation. We derive effective supergraph Feynman rules for them. Surprisingly, the Feynman rules for the non-chiral correlators are obtained from those for the chiral correlators by a simple Grassmann shift of the space-time variables. We rely on the formulation of the theory in Lorentz harmonic chiral (LHC) superspace elaborated in the twin paper arXiv:1601.06803. In this approach only the chiral half of the supersymmetry is manifest. The other half is realized by nonlinear and nonlocal transformations of the LHC superfields. However, at Born level only the simple linear part of the transformations is relevant. It corresponds to effectively working in the self-dual sector of the theory. Our method is also applicable to a wider class of supermultiplets like all the half-BPS operators and the Konishi multiplet.
