Loops and legs: ABJM amplitudes from -graphs
Song He, Yao-Qi Zhang
We initiate a systematic study on how to extract planar integrands of (supersymmetric) scattering amplitudes with loops and legs in Aharony-Bergman-Jafferis-Maldacena (ABJM…
A Hidden Permutation Symmetry of Squared Amplitudes in ABJM Theory
Song He, Canxin Shi, Yichao Tang +1
We define the square amplitudes in planar Aharony-Bergman-Jafferis-Maldacena theory (ABJM), analogous to that in super-Yang-Mills theory (SYM). Surprisingly, the…
Notes on conformal integrals: Coulomb branch amplitudes, magic identities and bootstrap
Song He, Xuhang Jiang, Jiahao Liu +1
We study multi-loop conformal integrals for four-point correlators of planar super-Yang-Mills theory, and in particular those contributing to Coulomb branch amplitudes…
The Cusp Limit of Correlators and A New Graphical Bootstrap for Correlators/Amplitudes to Eleven Loops
Song He, Canxin Shi, Yichao Tang +1
We consider the universal behavior of half-BPS correlators in super-Yang-Mills in the cusp limit where two consecutive separations become lightl…
