Radiative Classical Gravitational Observables at from Scattering Amplitudes

Enrico Herrmann, Julio Parra-Martinez, Michael S. Ruf +1

We compute classical gravitational observables for the scattering of two spinless black holes in general relativity and supergravity in the formalism of Kosower,…

Gravitational Bremsstrahlung from Reverse Unitarity

Enrico Herrmann, Julio Parra-Martinez, Michael S. Ruf +1

We compute the total radiated momentum carried by gravitational waves during the scattering of two spinless black holes at the lowest order in Newton's constant, ,…

Positive geometry, local triangulations, and the dual of the Amplituhedron

Enrico Herrmann, Cameron Langer, Jaroslav Trnka +1

We initiate the systematic study of \emph{local positive spaces} which arise in the context of the Amplituhedron construction for scattering amplitudes in planar maximally supersym…

Building Bases of Loop Integrands

Jacob L. Bourjaily, Enrico Herrmann, Cameron Langer +1

We describe a systematic approach to the construction of loop-integrand bases at arbitrary loop-order, sufficient for the representation of general quantum field theories. We provi…

Positive Geometries for One-Loop Chiral Octagons

Enrico Herrmann, Cameron Langer, Jaroslav Trnka +1

Inspired by the topological sign-flip definition of the Amplituhedron, we introduce similar, but distinct, positive geometries relevant for one-loop scattering amplitudes in planar…

Logarithmic forms and differential equations for Feynman integrals

Enrico Herrmann, Julio Parra-Martinez

We describe how a dlog representation of Feynman integrals leads to simple differential equations. We derive these differential equations directly in loop momentum or embedding spa…
