| Abstract: | Q2-evolution of the Bjorken sum rule in the resonance region is studied. The roles of the Roper resonance N* (1440) estimated by the constituent quark model and by the hybrid model are stressed. Moreover, the Q2- dependence of the Gerasimov-Drell-Hearn sum rule contributed by the resonances is also discussed. |
