论文摘要
在本文中，我们使用散射幅度的方法启动了多品味同理理论的研究。我们从不同的角度探讨了这个主题，并扩展到迄今为止使用的技术主要是在单品味的情况下。这包括软定理，具有非平凡的右侧的广义软定理，同进二元性，柔软的引导和奖励关系。我们在两个示例中演示了新的属性，分别是多品味的u（n）galileon和三培料U（2）/u（1）galileon。
In this paper, we initiate the study of multi-flavor Galileon theories using the methods of scattering amplitudes. We explore this topic from different perspectives and extend the techniques employed so far mainly in the single-flavor case. This includes soft theorems, generalized soft theorems with non-trivial right-hand side, Galileon dualities, soft bootstrap and bonus relations. We demonstrate new properties on two examples, the multi-flavor U(N) Galileon and the three-flavor U(2)/U(1) Galileon.
