The Proton Spin Structure Function g_2 and Generalized Polarizabilities in the Strong QCD Regime

The strong interaction is not well understood at low energy, or for interactions with low momentum transfer Q^2, but one of the clearest insights we have comes from Chiral Perturbation Theory (\chiPT). This effective treatment gives testable predictions for the nucleonic generalized polarizabilities -- fundamental quantities describing the nucleon's response... Show more
