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…
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…
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…
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…
