# Radiation reaction at the level of the action

@article{Birnholtz2014RadiationRA, title={Radiation reaction at the level of the action}, author={Ofek Birnholtz and Shahar Hadar and Barak Kol}, journal={International Journal of Modern Physics A}, year={2014}, volume={29}, pages={1450132} }

The aim of this paper is to highlight a recently proposed method for the treatment of classical radiative effects, in particular radiation reaction, via effective field theory methods. We emphasize important features of the method and in particular the doubling of fields. We apply the method to two simple systems: a mass–rope system and an electromagnetic charge-field system. For the mass–rope system in 1 + 1 dimensions we derive a double-field effective action for the mass which describes a… Expand
