Gravitational Effective Theories with Maximal Supersymmetry and a Peculiar Parity
Justin Berman, Simon Caron-Huot, Aditi V. Chandra +4
We study the space of four-dimensional ultraviolet completions for supergravity that are described at low energies by weakly-coupled effective field theories (EFTs)…
String Theory from Maximal Supersymmetry
Henriette Elvang, Aidan Herderschee, Roger Morales
We explore the space of non-gravitational, maximally supersymmetric, planar 4d effective field theories (EFTs) that have super Yang-Mills (SYM) at leading order. In…
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,…
Special Functions and Geometries in Scattering Amplitudes: From Particle Physics to Gravity
Roger Morales
This thesis focuses on the fields of scattering amplitudes and Feynman integrals, with an emphasis on the geometries and special functions that they involve, and is devoted to two…
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…
