ITMP Seminar "Spinning and spinless two-particle dynamics from gravitational scattering amplitudes"

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Mar 10, at 18:00 (Moscow time). The seminar will be arranged via Zoom.

Speaker: Prof. Radu Roiban, Penn State University

Title: Spinning and spinless two-particle dynamics from gravitational scattering amplitudes

Abstract: In the appropriate classical limit, scattering amplitude-based techniques can yield the classical interaction of massive bodies at fixed order in the post-Minkowskian expansion.

In this talk we review a framework for the construction of the two-body Hamiltonian for compact binary systems and illustrate it with state of the art results for both spinning and spinless systems. Throughout we emphasize structure of gravitational interactions and direct relations between scattering amplitudes and observables of two-particle dynamics.

If you want to join the seminar please register here before 15:00, March 10.
