Numerical Evaluation of One-Loop Scattering Amplitudes for Hard-Photon Emission in Bhabha Scattering

S. Actis, P. Mastrolia, G. Ossola

After a general introduction about the latest developments in the approach to multi-loop NLO calculations, we present a numerical evaluation of the one-loop QED corrections to the hard-bremsstrahlung emission in Bhabha scattering. The calculation is performed by employing the reduction method developed by Ossola, Papadopoulos and Pittau (OPP).
