The Two-loop Soft Anomalous Dimension Matrix and Resummation at Next-to-next-to Leading Pole

S. Mert Aybat, Lance J. Dixon, George Sterman

We extend the resummation of dimensionally-regulated amplitudes to next-to-next-to-leading poles. This requires the calculation of two-loop anomalous dimension matrices for color m…
