Two-loop corrections to
Z. Bern, A. De Freitas, L. Dixon
An overview of the calculation of the two-loop helicity amplitudes for scattering of two gluons into two photons is presented. These matrix elements enter into the recent improved…

Supersymmetric Regularization, Two-Loop QCD Amplitudes and Coupling Shifts
Z. Bern, A. De Freitas, L. Dixon +1
We present a definition of the four-dimensional helicity (FDH) regularization scheme valid for two or more loops. This scheme was previously defined and utilized at one loop. It am…

Two-Loop Helicity Amplitudes for Gluon-Gluon Scattering in QCD and Supersymmetric Yang-Mills Theory
Zvi Bern, Abilio De Freitas, Lance Dixon
We present the two-loop helicity amplitudes for the scattering of two gluons into two gluons in QCD, which are relevant for next-to-next-to-leading order corrections to jet product…
