我们证明了N = 6超共形Chern-Simons理论(ABJM)的四点和六点树能级振幅满足OSp(6| 4)对偶超共形对称,如果将对偶超空间扩大到包含三个额外的Grassmann偶坐标,它们对应于CP 3的阿贝尔等距。包含这些坐标使我们能够匹配的非平凡的对偶超共形发电机与一级杨格发电机时,作用于壳振幅。我们还讨论了环路级振幅的双重共形对称性的一些含义。
We demonstrate that the four and six-point tree-level amplitudes of N = 6 superconformal Chern-Simons theory (ABJM) enjoy OSp(6|4) dual superconformal symmetry if one enlarges the dual superspace to include three additional Grassmann-even coordinates which correspond to an abelian isometry of CP3. The inclusion of these coordinates enables us to match the nontrivial dual superconformal generators with level-one Yangian generators when acting on on-shell amplitudes. We also discuss some implications of dual conformal symmetry for loop-level amplitudes.
