Geometric Landau Analysis and Symbol Bootstrap

Dmitry Chicherin, Johannes Henn, Elia Mazzucchelli +3

We investigate how the positive geometry framework for loop integrands in $N = 4$ super Yang-Mills theory constrains the structure of the integrated answers. This is done…

All-loop Leading Singularities of Wilson Loops

Taro V. Brown, Johannes M. Henn, Elia Mazzucchelli +1

We study correlators of null, $n$ -sided polygonal Wilson loops with a Lagrangian insertion in the planar limit of the $N = 4$ supersymmetric Yang-Mills theory. This finite obs…

Two-loop four-point amplitudes on the Coulomb branch of $N = 4$ super Yang-Mills

Wojciech Flieger, Johannes Henn, Anders Schreiber +1

We explore scattering amplitudes on the Coulomb branch of maximally supersymmetric Yang-Mills theory. We introduce a particular pattern of scalar vacuum expectation values that all…
