Revealing Hidden Regions in Wide-Angle and Forward Scattering
Einan Gardi, Franz Herzog, Stephen Jones +1
We discuss a class of Feynman Integrals containing hidden regions that are not straightforwardly identified using the geometric, or Newton polytope, approach to the method of regio…

Dissecting polytopes: Landau singularities and asymptotic expansions in scattering
Einan Gardi, Franz Herzog, Stephen Jones +1
Parametric representations of Feynman integrals have a key property: many, frequently all, of the Landau singularities appear as endpoint divergences. This leads to a geometric int…
