DESCRIPTION:Title:\n\nFrom scattering amplitudes to Newton’s potential a
nd beyond \n\nAbstract: I will review the computation of the gravitationa
l potential from scattering amplitudes and unitarity. I will also explain
how to compute directly observable quantities such as the deflection angle
for light or for gravitons passing by a heavy mass (such as a black hole)
. After this introduction\, I will show how to extend our considerations t
o incorporate higher-derivative corrections to the Einstein-Hilbert theory
\, in the framework of effective field theories. Finally I will discuss th
e prospects of extending systematically such computations to higher loops
using a new\, gauge-invariant version of the color-kinematics BCJ duality
formulated directly in a heavy-mass effective theory (which will also be b
riefly discussed).\n\nZoom link: IPPP Seminars (Thursday at 2 pm UK tim
