Bootstrapping two-loop six-gluon amplitudes in QCD
Sérgio Carrôlo, Dmitry Chicherin, Johannes M. Henn +2
The maximally transcendental, or most complicated, terms of gauge-theory scattering amplitudes have long been singled out, following Lipatov and collaborators, as those parts of a…
Two-loop Six-point Planar Massless Feynman Integrals to Higher Orders
Yuanche Liu, Antonela Matijašić, Tiziano Peraro +3
In this work, we calculate two-loop six-point planar massless Feynman integrals at higher orders in the dimensional regulator , corresponding to higher transcendental weights. I…
Complete computation of all three-loop five-point massless planar integrals
Dmitry Chicherin, Yu Wu, Zihao Wu +3
We calculate all three-loop, five-point, massless planar Feynman integral families in the dimensional regularization scheme. This is a new milestone in Feynman integral computation…
Complete function space for planar two-loop six-particle scattering amplitudes
Johannes Henn, Antonela Matijašić, Julian Miczajka +3
We derive the full system of canonical differential equations for all planar two-loop massless six-particle master integrals, and determine analytically the boundary conditions. Th…
An Analytic Computation of Three-Loop Five-Point Feynman Integrals
Yuanche Liu, Antonela Matijašić, Julian Miczajka +3
We evaluate the three-loop five-point pentagon-box-box massless integral family in the dimensional regularization scheme, via canonical differential equation. We use tools from com…
A computation of two-loop six-point Feynman integrals in dimensional regularization
Johannes M. Henn, Antonela Matijašić, Julian Miczajka +3
We compute three families of two-loop six-point massless Feynman integrals in dimensional regularization, namely the double-box, the pentagon-triangle, and the hegaxon-bubble famil…
