Learning Feynman integrals from differential equations with neural networks
Francesco Calisto, Ryan Moodie, Simone Zoia
We perform an exploratory study of a new approach for evaluating Feynman integrals numerically. We apply the recently-proposed framework of physics-informed deep learning to train…
Two-loop five-particle scattering amplitudes
Simone Zoia
I discuss the recent advances in the computation of two-loop scattering amplitudes for five-particle processes. The latter are fundamental ingredients to obtain predictions at the…
Lepton-pair scattering with an off-shell and an on-shell photon at two loops in massless QED
Simon Badger, Jakub Kryś, Ryan Moodie +1
We compute the two-loop QED helicity amplitudes for the scattering of a lepton pair with an off-shell and an on-shell photon, , using the approximation of mas…
All Two-Loop Feynman Integrals for Five-Point One-Mass Scattering
Samuel Abreu, Dmitry Chicherin, Harald Ita +4
We compute the complete set of two-loop master integrals for the scattering of four massless particles and a massive one. Our results are ready for phenomenological applications, r…
Scattering Amplitudes in Quantum Field Theory
Simon Badger, Johannes Henn, Jan Plefka +1
These lecture notes bridge a gap between introductory quantum field theory (QFT) courses and state-of-the-art research in scattering amplitudes. They cover the path from basic defi…
Isolated photon production in association with a jet pair through next-to-next-to-leading order in QCD
Simon Badger, Michal Czakon, Heribertus Bayu Hartanto +4
In this work, we provide a comprehensive set of differential cross-section distributions for photon + di-jet production in proton-proton collisions with next-to-next-to-leading ord…
-Module Techniques for Solving Differential Equations in the Context of Feynman Integrals
Johannes Henn, Elizabeth Pratt, Anna-Laura Sattelberger +1
Feynman integrals are solutions to linear partial differential equations with polynomial coefficients. Using a triangle integral with general exponents as a case in point, we compa…
