Color Decompositions of the Two Loop Amplitudes of Yang-Mills theory
David C. Dunbar
The color structure of two-loop gluon amplitudes is examined both from a color trace basis expansion and an alternative based upon structure constants. We use use this as a vehicle…

The Seven-Point Two-Loop Full-Color All-Plus Helicity Yang-Mills Amplitude
Adam R. Dalgleish, David C. Dunbar, Warren B. Perkins +1
The seven-gluon two-loop full-color Yang-Mills amplitude is presented in a compact analytic form where we use the methods of four-dimensional unitarity cuts to obtain the polylogar…
