The spin-holonomy map and the gyrogravitomagnetic ratios at the second post-Minkowskian approximation in binary systems

Abstract

We show how to compute the rotation, during a scattering encounter, of the spins of two gravitationally interacting particles at the second post-Minkowskian order. This result will allow improvement of the knowledge of the spin-orbit sector of the effective one-body Hamiltonian description of the dynamics of spinning binary systems.
