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…

Dirac brackets for classical radiative observables
Francesco Alessio, Riccardo Gonzo, Canxin Shi
We introduce a new coherent state expansion of the exponential representation of the S-matrix for the classical gravitational two-body problem. By combining the Kosower-Maybee-O'Co…

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…
