DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CMU-TP/39/">
 Gravitational Bremsstrahlung in the Post-Minkowskian expansion</a>\nby Mas
 similiano-Maria Riva (IPhT) as part of Carnegie Mellon theoretical physics
 \n\n\nAbstract\nI will discuss the scattering of two compact objects inter
 acting via gravity\, using the so-called world-line Effective Field Theory
  approach in the post-Minkowskian expansion (i.e. expanding in the Newton'
 s constant G but not in the velocities). In particular\, I will focus on t
 he computation of classical observables such as the total emitted momentum
 . This is obtained by phase-space integration of the graviton momentum wei
 ghted by the modulo squared of the radiation amplitude. It can be recast a
 s an effective cut two-loop integral that I will solve using techniques bo
 rrowed from particle physics.\n
