    Ryan Moodie (Turin University)

    We present an analytic computation of $e^+e^-\to\gamma\gamma^*$ at two loops in massless QED. We reconstruct the analytic form of the amplitudes from numerical evaluations over finite fields. We express the integrals in a basis of Goncharov polylogarithms to obtain compact expressions. These contributions are required for N$^3$LO predictions of the inclusive process $e^+e^-\to\gamma^*$ and for...

  13. 16. Photon splitting corrections to soft-photon resummation
    Lois Flower (Durham University)
    09/06/2023, 14:30

    In this talk I will motivate the importance of including QED corrections in a systematic and automated manner. I will present an algorithm to add photon-splitting corrections to the Yennie-Frautschi-Suura-style soft-photon resummation available in the Sherpa Monte-Carlo event generator. Then, I will introduce different lepton dressing strategies which incorporate further leptons and hadrons in...
