论文摘要
我们引入了D维矢量振幅的分解，从保留父级理论的所有部分幅度关系的构件方面。使用这种分解，我们得出了非线性Sigma模型PION与Yang-Mills-Scalar理论的纯量表之间的新幅度关系。这些新的关系表明，出生的二元性不变性与爱因斯坦 - 麦克斯韦理论的等效性，考虑到其与扬·米尔斯（Yang Mills）的两种标量理论中已知的双拷贝结构。该观察结果激发了一个通用框架，用于使用我们振幅分解中的构建块以任何多重性构建双重不变的有效现场理论。最后，我们猜想了这些双重不变的构建块与n = 4个超级阳米尔斯的骨骼扇区之间的微妙关系。
We introduce a decomposition of D-dimensional vector amplitudes in terms of building blocks that preserve all partial amplitude relations of the parent gauge-theory. Using this decomposition, we derive a new set of amplitude relations between nonlinear sigma model pions and the pure-scalar sector of Yang-Mills-scalar theory. These new relations indicate an equivalence between Born-Infeld duality invariance and that of Einstein-Maxwell theory, considering their known double-copy construction from the two scalar theories with Yang Mills. This observation motivates a general framework for constructing duality-invariant effective field theory observables at any multiplicity using the building blocks in our amplitude decomposition. Finally, we conjecture a subtle relationship between these duality-invariant building blocks and the bosonic sector of N=4 super Yang-Mills.
