Informal HEP Journal club: An action for reaction: effective field theory study of post-Newtonian radiative effects

Presented by Shahar Hadar, Hebrew U, Jerusalem

2 December 2013 13:00 in CM219

We present an effective field theory (EFT) describing radiation and radiation-reaction effects in the post-Newtonian approximation of General Relativity. Our formulation allows a unified treatment of outgoing radiation and its reaction force within an action formalism, and significantly economizes extant derivations. New results on radiation and reaction in general spacetime dimensions, obtained within our EFT, will be presented. In particular, the difference between even and odd spacetime dimensions in our context will be discussed. Finally, we will comment on the availability of a similar EFT treatment for near-extremal black holes.
