15. Calabi-Yau Meets Gravity: Feynman Integral Geometries in Gravitational Waves

Matthias Wilhelm (University of Copenhagen)

12/12/2023, 14:00

Multi-loop Feynman integrals for collider physics are known to contain intricate geometries and to evaluate to complicated transcendental numbers and functions. In this talk, I will investigate Feynman integrals contributing to the emission of gravitational waves up to fifth order in the post-Minkowskian expansion, identifying new geometries that lead to new transcendental functions.

Multi-loop Feynman integrals are crucial in meeting the requirements for high-precision predictions of both collider and gravitational-wave experiments. Such integrals are associated to geometries, providing information about the function classes appearing in their evaluation. In this talk I will discuss integrals associated to hyperelliptic curves, a natural generalization of elliptic curves....
