# Radiation reaction and gravitational waves in the effective field theory approach

@article{Galley2009RadiationRA, title={Radiation reaction and gravitational waves in the effective field theory approach}, author={Chad R. Galley and Manuel Tiglio}, journal={Physical Review D}, year={2009}, volume={79}, pages={124027} }

We compute the contribution to the Lagrangian from the leading order (2.5 post-Newtonian) radiation reaction and the quadrupolar gravitational waves emitted from a binary system using the effective field theory (EFT) approach of Goldberger and Rothstein. We use an initial value formulation of the underlying (quantum) framework to implement retarded boundary conditions and describe these real-time dissipative processes. We also demonstrate why the usual scattering formalism of quantum field… Expand
