Two-loop helicity amplitudes in QCD
We compute the σ(α3/8) virtual QCD corrections for the process e+e- →qqg arising from the interference of the two-loop and tree amplitudes and from the self-interference of the one-loop amplitude. The results are presented in the form of both matrix elements and helicity amplitudes. The calculation...
