Evaluation of Feynman integrals for scattering observables relevant for gravitational physics

Objective

This work focuses on the evaluation of integrals encountered in Post-Minkowskian perturbative expansion of gravitational observables, using the modern scattering amplitude techniques. In particular, we encounter integrals having a very complicated analytic structure in the form of integrals containing elliptic curves. These integrals are one of the main bottlenecks in the present computations. The aim is to utilise studies from collider physics to evaluate these integrals.
