The Two-loop MHV Momentum Amplituhedron from Fibrations of Fibrations
Livia Ferro, Ross Glew, Tomasz Lukowski +1
Recently, a new approach to computing the canonical forms of the momentum amplituhedron in dual-momentum space was proposed by the authors. These are relevant for the integrands of…

Prescriptive Unitarity from Positive Geometries
Livia Ferro, Ross Glew, Tomasz Lukowski +1
In this paper, we define the momentum amplituhedron in the four-dimensional split-signature space of dual momenta. It encodes scattering amplitudes at tree level and loop integrand…

Pushforwards via Scattering Equations with Applications to Positive Geometries
Tomasz Lukowski, Robert Moerman, Jonah Stalknecht
In this paper we explore and expand the connection between two modern descriptions of scattering amplitudes, the CHY formalism and the framework of positive geometries, facilitated…
