论文摘要
众所周知，$ \ Mathcal {n} = 8 $ SuperGravity是双重\ \ Mathcal {n} = 4 $ super yang-mills（sym）通过双复制关系。使用这两个理论中的散射幅度之间的显式关系，我们计算出$ \ Mathcal {n} = 8 $ supergravity中的软和界线限制，从$ \ mathcal {n} = 4 $ sym中。在我们使用双副本的应用中，选择了特定的自偶性条件，以使我们能够约束和确定界限限制中超级加重状态的R-对称指标。
It is known that $\mathcal{N}=8$ supergravity is dual to $\mathcal{N}=4$ super Yang-Mills (SYM) via the double copy relation. Using the explicit relation between scattering amplitudes in the two theories, we calculate the soft and collinear limits in $\mathcal{N}=8$ supergravity from know results in $\mathcal{N}=4$ SYM. In our application of double copy, a particular self-duality condition is chosen for scalars that allows us to constrain and determine the R-symmetry indices of the supergravity states in the collinear limit.
