Radiated Angular Momentum and Dissipative Effects in Classical Scattering.

We present a new formula for the angular momentum J^{μν} carried away by gravitational radiation in classical scattering. This formula, combined with the known expression for the radiated linear momentum P^{μ}, completes the set of radiated Poincaré charges due to scattering. We parametrize P^{μ} and J^{μν} by nonperturbative form factors and derive exact relations using the Poincaré algebra.
