Gravitational radiation-reaction in arbitrary dimension

Research output: Contribution to journalArticlepeer-review


We use effective field theory tools to study nonconservative effects in the gravitational two-body problem in general spacetime dimension. Using the classical version of the Closed Time Path formalism, we treat both the radiative gravitational field and its dynamical sources within a single action principle. New results include the radiation-reaction effective action in arbitrary dimensions to leading and +1PN orders, as well as the generalized quadrupole formula to order +1PN.
