n -point QCD two-loop amplitude

n -point QCD two-loop amplitude

We present an explicit expression for a particular n -gluon two-loop scattering partial amplitude. Specifically we present an analytic form for the single-trace Nc-independent color partial amplitude for the case where all external gluons have positive helicity.
