A KLT-like construction for multi-Regge amplitudes

Konstantin Baune, Johannes Broedel

Inspired by the calculational steps originally performed by Kawai, Lewellen and Tye, we decompose scattering amplitudes with single-valued coefficients obtained in the multi-Regge-…

Functions Beyond Multiple Polylogarithms for Precision Collider Physics

Jacob L. Bourjaily, Johannes Broedel, Ekta Chaubey +14

Feynman diagrams constitute one of the essential ingredients for making precision predictions for collider experiments. Yet, while the simplest Feynman diagrams can be evaluated in…

Meromorphic modular forms and the three-loop equal-mass banana integral

Johannes Broedel, Claude Duhr, Nils Matthes

We consider a class of differential equations for multi-loop Feynman integrals which can be solved to all orders in dimensional regularisation in terms of iterated integrals of mer…

A geometrical framework for amplitude recursions: bridging between trees and loops

Johannes Broedel, André Kaderli

Various methods for the recursive evaluation of scattering amplitudes in quantum field theory and string theory have been put forward during the last couple of years. In these proc…

Two dialects for KZB equations: generating one-loop open-string integrals

Johannes Broedel, André Kaderli, Oliver Schlotterer

Two different constructions generating the low-energy expansion of genus-one configuration-space integrals appearing in one-loop open-string amplitudes have been put forward in \rc…

Amplitude recursions with an extra marked point

Johannes Broedel, Andre Kaderli

The recursive calculation of Selberg integrals by Aomoto and Terasoma using the Knizhnik-Zamolodchikov equation and the Drinfeld associator makes use of an auxiliary point and faci…
