Title: General Relativity from Worldline QFT

Abstract:

I will discuss how gravitational wave physics can be derived from amplitudes in QFT.
I will then focus on the recently established worldline QFT (WQFT) which is an efficient way of deriving the classical limit of amplitudes as well as including effects beyond spinless point-like bodies.

After this introductory part, I will present our recent results on the leading-order gravitational waveform in the Post-Minkowskian expansion.
Here, I will include results beyond our recent paper including spinning bodies and a fully covariant waveform derived from a WQFT with a hidden supersymmetry.
Depending on the time, I will also consider some generic questions on motion of point-like particles in gravitational fields.
