Gerasimov-Drell-Hearn sum rule and related integrals - art. no. 114010

The spin structure of the nucleon resonance region is analyzed on the basis of our phenomenological model MAID. Predictions are given for the Gerasimo v-Drell-Hearn sum rule as well as generalized integrals over spin structure functions. The dependence of these integrals on momentum transfer is studi ed and rigorous relationships between various definitions of generalized Ge rasimov-Drell-Hearn integrals and spin polarizabilities are derived. These results are compared to the predictions of chiral perturbation theory and p henomenological models.
