$\mathcal{N}=4$ SYM理论扭量形式中的复合算子

Composite Operators in the Twistor Formulation of $\mathcal{N}=4$ SYM Theory

Laura Koster, Vladimir Mitev, Matthias Staudacher, Matthias Wilhelm

摘要:

我们将规范不变的局部复合算子的扭曲空间制定的$\mathcal{N}=4$超级杨米尔斯理论。在这个公式中,基本领域的相互作用被重组成无限多个相互作用顶点,我们认为,这同样适用于复合算子。为了检验我们在扭量空间中的局部复合算子的定义,我们计算了几个相应的形状因子,从而也开始了使用位置扭量空间框架的形状因子的研究。在这封信中,我们使用由两个相同的复标量构建的复合算子作为教学示例;我们在后续论文中处理一般情况。

英文摘要:

We incorporate gauge-invariant local composite operators into the twistor-space formulation of $\mathcal{N}=4$ Super Yang-Mills theory. In this formulation, the interactions of the elementary fields are reorganized into infinitely many interaction vertices and we argue that the same applies to composite operators. To test our definition of the local composite operators in twistor space, we compute several corresponding form factors, thereby also initiating the study of form factors using the position twistor-space framework. Throughout this letter, we use the composite operator built from two identical complex scalars as a pedagogical example; we treat the general case in a follow-up paper.
