Low energy theorem for virtual Compton scattering and generalized sum rules of the nucleon
arXiv:0807.3791 · doi:10.1103/PhysRevLett.101.141601
Abstract
We formulate the low energy theorem for virtual Compton scattering off a nucleon and examine its consequences for generalized nucleon polarizabilites. As a result of a new, model independent definition of the low energy limit for VVCS reaction, all generalized sum rules of the nucleon have continuous limit for real photons and obtain contributions from the -channel that were not included previously.
