Towards a microscopic understanding of nucleon polarizabilities
arXiv:1601.04154 · doi:10.1007/s00601-016-1046-8
Abstract
We outline a microscopic framework to calculate nucleon Compton scattering from the level of quarks and gluons within the covariant Faddeev approach. We explain the connection with hadronic expansions of the Compton scattering amplitude and discuss the obstacles in maintaining electromagnetic gauge invariance. Finally we give preliminary results for the nucleon polarizabilities.
