论文摘要
我们对巨大的自旋2“ graviton”的自我互动进行系统研究,最多与$ \ Mathcal {n} = 4 $ supersymmetry。使用最近开发的大型壳上超空间形式主义,我们以所有超对称性和洛伦兹的不变性表现出来的形式构建了最通用的立方体大型重力振幅。我们发现,对于$ \ Mathcal {n} \ geq 3 $ supersymmetry,始终如一的互动家族与无幽灵的DRGT模型相吻合。对于$ \ mathcal {n} = 4 $(最大)超对称性,有一个一致的立方相互作用,它与没有渐近超质量的独特结构相吻合。此外,我们讨论了在高能极限,与超对称速气的连接以及超对称性大型双拷贝的可能性中相互作用的结构。
We initiate a systematic study of the self-interactions of a massive spin-2 "graviton" consistent with up to $\mathcal{N}=4$ supersymmetry. Using a recently developed massive on-shell superspace formalism, we construct the most general set of cubic massive graviton amplitudes in a form with all supersymmetry and Lorentz invariance manifest. We find that for $\mathcal{N}\geq 3$ supersymmetry, the family of consistent interactions coincide with those of the ghost-free dRGT model. For $\mathcal{N}=4$ (maximal) supersymmetry there is a single consistent cubic interaction which coincides with the unique structure required for the absence of asymptotic superluminality. Additionally, we discuss the structure of interactions in the high-energy limit, connections to supersymmetric Galileons and the possibility of a supersymmetric massive double copy.
