Grassmannian Geometries for Non-Planar On-Shell Diagrams
Artyom Lisitsyn, Umut Oktem, Melissa Sherman-Bennett +1
On-shell diagrams are gauge invariant quantities which play an important role in the description of scattering amplitudes. Based on the principles of generalized unitarity, they ar…
Tree-Level Gravity Amplitudes at Infinity
Justin Lemmon, Jaroslav Trnka
In this note we study on-shell tree-level gravity amplitudes in the infinite momentum limit. In the case of the two-line BCFW shift, we have a famous improved behavior at infinity…
Geometric Landau Analysis and Symbol Bootstrap
Dmitry Chicherin, Johannes Henn, Elia Mazzucchelli +3
We investigate how the positive geometry framework for loop integrands in super Yang-Mills theory constrains the structure of the integrated answers. This is done…
Universality of Colored Scalars from the Stringy KLT Kernel
Christoph Bartsch, Karol Kampf, Jiří Novotný +1
A new perspective on the inverse string theory Kawai-Lewellen-Tye (KLT) kernel is provided which establishes the universality of scattering amplitudes in the bi-adjoint scalar (BAS…
All-loop Leading Singularities of Wilson Loops
Taro V. Brown, Johannes M. Henn, Elia Mazzucchelli +1
We study correlators of null, -sided polygonal Wilson loops with a Lagrangian insertion in the planar limit of the supersymmetric Yang-Mills theory. This finite obs…
Two-loop four-point amplitudes on the Coulomb branch of 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…
