Canonical differential equations for the elliptic two-loop five-point integral family relevant to jet production at leading colour
Matteo Becchetti, Christoph Dlapa, Simone Zoia
We present differential equations (DEs) in canonical form for a family of two-loop five-point Feynman integrals containing elliptic functions and nested square roots. This is the o…
Two-Loop Five-Point Two-Mass Planar Integrals and Double Lagrangian Insertions in a Wilson Loop
Samuel Abreu, Dmitry Chicherin, Vasily Sotnikov +1
We consider the complete set of planar two-loop five-point Feynman integrals with two off-shell external legs. These integrals are relevant, for instance, for the calculation of th…
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…
-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…
Anomalous Ward identities for on-shell amplitudes at the conformal fixed point
Dmitry Chicherin, Johannes Henn, Simone Zoia
Conformal symmetry underlies many massless quantum field theories, but little is known about the consequences of this powerful symmetry for on-shell scattering amplitudes. Working…
Multi-Regge Limit of the Two-Loop Five-Point Amplitudes in Super Yang-Mills and Supergravity
Simon Caron-Huot, Dmitry Chicherin, Johannes Henn +2
In previous work, the two-loop five-point amplitudes in super Yang-Mills theory and supergravity were computed at symbol level. In this paper, we co…
