The spectrum of Feynman-integral geometries at two loops
Piotr Bargiela, Hjalte Frellesvig, Robin Marzucca +4
We provide a complete classification of the Feynman-integral geometries at two-loop order in four-dimensional Quantum Field Theory with standard quadratic propagators. Concretely,…
Classification of Feynman integral geometries for black-hole scattering at 5PM order
Daniel Brammer, Hjalte Frellesvig, Roger Morales +1
We provide a complete classification of the Feynman integral geometries relevant to the scattering of two black holes at fifth order in the post-Minkowskian (PM) expansion, i.e. at…
Calabi-Yau Feynman integrals in gravity: -factorized form for apparent singularities
Hjalte Frellesvig, Roger Morales, Sebastian Pögel +2
We study a recently identified four-loop Feynman integral that contains a three-dimensional Calabi-Yau geometry and contributes to the scattering of black holes in classical gravit…
Classifying post-Minkowskian geometries for gravitational waves via loop-by-loop Baikov
Hjalte Frellesvig, Roger Morales, Matthias Wilhelm
We use the loop-by-loop Baikov representation to investigate the geometries in Feynman integrals contributing to the classical dynamics of a black-hole two-body system in the post-…
Calabi-Yau meets Gravity: A Calabi-Yau three-fold at fifth post-Minkowskian order
Hjalte Frellesvig, Roger Morales, Matthias Wilhelm
We study geometries occurring in Feynman integrals that contribute to the scattering of black holes in the post-Minkowskian expansion. These geometries become relevant to gravitati…
