Abstract
We investigate the Drell-Hearn-Gerasimov sum rule within a relativistic constituent quark model based on the light-front formalism.The contribution of the nucleon to Delta transition is explicitly evaluated using different forms of the baryon wave functions and adopting a one-body relativistic current which includes Dirac and Pauli form factors for the constituent quarksFile in questo prodotto:
