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…
Two-loop leading colour QCD helicity amplitudes for top quark pair production in the gluon fusion channel
Simon Badger, Ekta Chaubey, Heribertus Bayu Hartanto +1
We present a complete set of analytic helicity amplitudes for top quark pair production via gluon fusion at two-loops in QCD. For the first time, we include corrections due to mass…
Three-loop contributions to the parameter and iterated integrals of modular forms
Samuel Abreu, Matteo Becchetti, Claude Duhr +1
We compute fully analytic results for the three-loop diagrams involving two different massive quark flavours contributing to the parameter in the Standard Model. We find that t…
All-order amplitudes at any multiplicity in the multi-Regge limit
V. Del Duca, S. Druc, J. M. Drummond +5
We propose an all-loop expression for scattering amplitudes in planar N=4 super Yang-Mills theory in multi-Regge kinematics valid for all multiplicities, all helicity configuration…
An analytic solution for the equal-mass banana graph
Johannes Broedel, Claude Duhr, Falko Dulat +3
We present fully analytic results for all master integrals for the three-loop banana graph with four equal and non-zero masses. The results are remarkably simple and all integrals…
Amplitudes in the Multi-Regge Limit of N=4 SYM
Vittorio Del Duca, Stefan Druc, James Drummond +5
A novel way of computing high-order amplitudes in the multi-Regge limit of planar maximally supersymmetric Yang-Mills theory is presented. In this framework, we are able to obtain…
