Two-loop QED corrections to the scattering of four massive leptons
Maximilian Delto, Claude Duhr, Lorenzo Tancredi +1
We study two-loop corrections to the scattering amplitude of four massive leptons in quantum electrodynamics. These amplitudes involve previously unknown elliptic Feynman integrals…

Topology and geometry of elliptic Feynman amplitudes
Claude Duhr, Yu Jiao Zhu
We report on the analytic computation of the 2-loop amplitude for Bhabha scattering in QED. We study the analytic structure of the amplitude, and reveal its underlying connections…
