Description
I will discuss the calculation of the impulse at fifth Post Minkowksian order at first self force order including both conservative and dissipative effects in the Worldline Quantum Field Theory formalism. The difficulty in this 4 loop calculation lies in the appearing Feynman integrals. On the one hand the IBP reduction is a major technical obstacle to overcome. On the other hand periods over a Calabi-Yau threefold contribute for a first time to a physical observable. I will discuss how to effectively handle this new type of functions using the method of differential equations.
