DESCRIPTION:Speakers: Stefano De Angelis (IPhT\, Saclay)\n\nIn the first p
 art of my talk\, I will introduce the physical setup: the computation of g
 ravitational waveforms emitted in hyperbolic encounters\, and the need for
  representations that are both analytically tractable and suitable for num
 erical evaluation. These computations can be approached by generalising te
 chniques originally developed in the context of high-precision collider ph
 ysics\, in particular methods for simplifying and evaluating the relevant 
 integrals.Thus\, I will discuss singularity-free Feynman integral bases\, 
 designed so that integration-by-parts reductions do not introduce coeffici
 ents singular in the dimensional regulator. Such bases can simplify the st
 ructure of amplitudes and related observables\, and provide useful lessons
  for the organisation of gravitational waveform computations\, as well as 
 for collider observables.\n\nhttps://indico.zdv.uni-mainz.de/event/107/
