The two-loop QCD matrix element for e^+e^->3 jets (2002)
Journal Article
Garland, L., Gehrmann, T., Glover, E., Koukoutsakis, A., & Remiddi, E. (2002). The two-loop QCD matrix element for e^+e^->3 jets. Nuclear Physics B, 627(1-2), 107-188. https://doi.org/10.1016/s0550-3213%2802%2900057-3

We compute the O(α3 s ) virtual QCD corrections to the γ ∗ →q ¯ qg matrix element arising from the interference of the two-loop with the tree-level amplitude and from the self-interference of the one-loop amplitude. The calculation is performed by re... Read More about The two-loop QCD matrix element for e^+e^->3 jets.

Two-loop QCD corrections to the scattering of massless distinct quarks (2001)
Journal Article
Anastasiou, C., Glover, E., Oleari, C., & Tejeda-Yeomans, M. (2001). Two-loop QCD corrections to the scattering of massless distinct quarks. Nuclear Physics B, 601(1-2), 318-340. https://doi.org/10.1016/s0550-3213%2801%2900079-7

We present the two-loop virtual QCD corrections to the scattering of distinct massless quarks, , in conventional dimensional regularisation. The structure of the infrared divergences agrees with that predicted by Catani while expressions for the fini... Read More about Two-loop QCD corrections to the scattering of massless distinct quarks.
