Maxwell-Einstein和Yang-Mills-Einstein超引力中振幅的简化

Simplifying amplitudes in Maxwell-Einstein and Yang-Mills-Einstein supergravities

Marco Chiodaroli

摘要:

本文综述了N=2超对称性超引力理论中散射振幅的双拷贝结构在5维和4维时空中的最新进展。特别注意的是致力于无限家庭的麦克斯韦-爱因斯坦理论与对称和均匀的目标空间和杨米尔斯-爱因斯坦理论与紧凑的规范群。本文还讨论了该构造对自发破缺规范对称性理论的推广。

英文摘要:

This article reviews recent progress in formulating double-copy constructions for scattering amplitudes in supergravity theories with N=2 supersymmetry in five and four spacetime dimensions. Particular attention is devoted to infinite families of Maxwell-Einstein theories with symmetric and homogeneous target spaces and to Yang-Mills-Einstein theories with compact gauge groups. Extension of the construction to theories with spontaneously-broken gauge symmetry is also discussed.
