论文摘要
最近的作品探讨了量子自偶摩尔斯理论中的散射幅度和自dual重力如何被解释为由W. Bardeen首先提出的异常引起的。我们在理论的轻态规格中研究了这个问题。首先，我们描述了如何校正与经典集成性相关的无限塔，表现出单循环异常。其次，我们提出了值得振幅简单的量子校正的轻曲线，这是基于最近描述扭曲空间异常的作品的基础。最后，我们发现了（循环集成）振幅的意外BCJ般的双复制，与循环集成的众所周知的BCJ双复制不同。
Recent works have explored how scattering amplitudes in quantum self-dual Yang-Mills theory and self-dual gravity can be interpreted as resulting from an anomaly, as first proposed by W. Bardeen. We study this problem in the light-cone-gauge formulation of the theories. Firstly, we describe how the infinite tower of symmetries associated to classical integrability can be quantum corrected, exhibiting the one-loop anomaly. Secondly, we present quantum-corrected light-cone Lagrangians worthy of the simplicity of the amplitudes, building on recent works describing the anomaly in twistor space. Finally, we discover an unexpected BCJ-like double copy for the (loop-integrated) amplitudes, distinct from the well-known BCJ double copy for the loop integrands.
