Scattering Amplitudes and Simple Canonical Forms for Simple Polytopes
Giulio Salvatori, Stefan Stanojevic
We provide an efficient recursive formula to compute the canonical forms of arbitrary -dimensional simple polytopes, which are convex polytopes such that every vertex lies preci…
The complete set of two-loop master integrals for Higgs + jet production in QCD
Hjalte Frellesvig, Martijn Hidding, Leila Maestri +2
In this paper we complete the computation of the two-loop master integrals relevant for Higgs plus one jet production initiated in arXiv:1609.06685, arXiv:1907.13156, arXiv:1907.13…
Evaluating two-loop non-planar master integrals for Higgs + jet production with full heavy-quark mass dependence
R. Bonciani, V. Del Duca, H. Frellesvig +6
We present the analytic computation of a family of non-planar master integrals which contribute to the two-loop scattering amplitudes for Higgs plus one jet production, with full h…
1-loop Amplitudes from the Halohedron
Giulio Salvatori
We recently proposed the Halohedron to be the 1-loop Amplituhedron for planar theory. Here we prove this claim by showing how it is possible to extract the integrand for the…
Hyperbolic Geometry and Amplituhedra in 1+2 dimensions
Giulio Salvatori, Sergio Cacciatori
Recently, the existence of an Amplituhedron for tree level amplitudes in the bi-adjoint scalar field theory has been proved by Arkhani-Hamed et al. We argue that hyperbolic geometr…
