Universal structure of radiative QED amplitudes at one loop
Tim Engel, Adrian Signer, Yannick Ulrich
We present two novel results about the universal structure of radiative QED amplitudes in the soft and in the collinear limit. On the one hand, we extend the well-known Low-Burnett…
Bhabha scattering at NNLO with next-to-soft stabilisation
Pulak Banerjee, Tim Engel, Nicolas Schalch +2
A critical subject in fully differential QED calculations originates from numerical instabilities due to small fermion masses that act as regulators of collinear singularities. At…
Møller scattering at NNLO
Pulak Banerjee, Tim Engel, Nicolas Schalch +2
We present a calculation of the full set of next-to-next-to-leading-order QED corrections to unpolarised Møller scattering. This encompasses photonic, leptonic, and non-perturbativ…
