Two-Loop QCD Helicity Amplitudes for $e^+e^- \to 3$ Jets
We compute the two-loop QCD helicity amplitudes for the process $e^+e^- \to q\bar q g$. The amplitudes are extracted in a scheme-independent manner from the coefficients appearing in the general tensorial structure for this process. The tensor coefficients are derived from the Feynman graph amplitud...
