All-Multiplicity Non-Planar MHV Amplitudes in sYM at Two Loops
arXiv:1911.09106 · doi:10.1103/PhysRevLett.124.111603
Abstract
We give a closed-form, prescriptive representation of all-multiplicity two-loop MHV amplitude integrands in fully-color-dressed (non-planar) maximally supersymmetric Yang-Mills theory.
Corrected a sign mistake for the pentabox numerators (table IV). Minor improvements and references added in v2. 4+3 pages, 22 figures, 4 tables, infinity of new amplitudes. Ancillary files contain a Mathematica implementation of our result
