Loop-Level Double Copy Relations from Forward Limits
Qu Cao, Song He, Yong Zhang +1
We study double copy relations for loop integrands in gauge theories and gravity based on their constructions from single cuts, which are in turn obtained from forward limits of lo…
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…
Superstring amplitudes meet surfaceology
Qu Cao, Jin Dong, Song He +1
We reformulate tree-level amplitudes in open superstring theory (type-I) in terms of stringy Tr amplitudes with various kinematical shifts in the "curve-integral" formulatio…
The Four-Point Correlator of Planar sYM at Twelve Loops
Jacob L. Bourjaily, Song He, Canxin Shi +1
We determine the 4-point correlation function and amplitude in planar, maximally supersymmetric Yang-Mills theory to 12 loops. We find that the recently-introduced 'double-triangle…
