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…
QCD Scattering Amplitudes and Prescriptive Unitarity
Sérgio Carrôlo, Dmitry Chicherin, Johannes Henn +2
We present a systematic framework for the maximally-transcendental part of planar QCD scattering amplitudes and perform the first bootstrap computation of six-gluon MHV amplitudes…
How gluon leading singularities discover curves on surfaces
Sérgio Carrôlo, Carolina Figueiredo
We study the leading singularities for pure gluon amplitudes obtained by on-shell gluing of three-particle amplitudes for an arbitrary graph in any number of dimensions. By encodin…
Bootstrapping Six-Gluon QCD Amplitudes
Sérgio Carrôlo, Dmitry Chicherin, Johannes Henn +2
We present a symbol-level bootstrap construction of the planar, two-loop six-gluon scattering amplitude for the --++++ helicity configuration in QCD, focusing on the maximal weight…
Hexagonal Wilson loop with Lagrangian insertion at two loops in super Yang-Mills theory
Sérgio Carrôlo, Dmitry Chicherin, Johannes Henn +2
In this work, we compute the two-loop result of the null hexagonal Wilson loop with a Lagrangian insertion in planar, maximally supersymmetric Yang-Mills theory via a bootstrap app…
