N=4的超级Yang-Mills的可积振幅变形与ABJM理论

Integrable Amplitude Deformations for N=4 Super Yang-Mills and ABJM Theory

Till Bargheer, Yu-tin Huang, Florian Loebbert, Masahito Yamazaki

摘要:

研究了4d N=4超对称Yang-Mills理论和3d N=6 Aharony-Bergman-Jafferis-Maldacena(ABJM)理论中散射振幅的杨氏不变形变.特别地,我们得到了4dN =4超Yang-Mills理论在动量和动量扭量空间中的变形格拉斯曼积分.对于三维ABJM理论,我们首先研究了形变散射振幅。我们研究了壳上图的一般变形,并找到了这个理论的变形格拉斯曼积分。我们还介绍了ABJM理论的变形Yangian不变量的代数R-矩阵构造。

英文摘要:

We study Yangian-invariant deformations of scattering amplitudes in 4d N=4 supersymmetric Yang-Mills theory and 3d N=6 Aharony-Bergman-Jafferis-Maldacena (ABJM) theory. In particular, we obtain the deformed Grassmannian integral for 4d N=4 super Yang-Mills theory, both in momentum and momentum-twistor space. For 3d ABJM theory, we initiate the study of deformed scattering amplitudes. We investigate general deformations of on-shell diagrams, and find the deformed Grassmannian integral for this theory. We furthermore introduce the algebraic R-matrix construction of deformed Yangian invariants for ABJM theory.
