Proton spin polarizabilities from polarized Compton scattering
arXiv:0705.0282 · doi:10.1103/PhysRevC.76.015203
Abstract
Polarized Compton scattering off the proton is studied within the framework of subtracted dispersion relations for photon energies up to 300 MeV. As a guideline for forthcoming experiments, we focus the attention on the role of the proton's spin polarizabilities and investigate the most favorable conditions to extract them with a minimum of model dependence. We conclude that a complete separation of the four spin polarizabilities is possible, at photon energies between threshold and the region, provided one can achieve polarization measurements with an accuracy of a few percent.
