Abstract
We detail the calculation of two-loop all-plus helicity amplitudes for pure Yang-Mills theory.The four dimensional unitarity methods and augmented recursion techniques we have developed, together with a knowledge of the singular structure of the amplitudesallow us to compute thesein compact analytic...
