โœฆ Synopsis

We present predictions for the spin structure functions of the proton in the framework of a unitary isobar model for one-pion photo-and electroproduction. Our results are compared with recent experimental data from SLAC. The first moments of the calculated structure functions fullfil the Gerasimov-Drell-Hearn and Burkhardt-Cottingham sum rules within an error of typically 5-10%.

Q 2 -evolution of the nucleon spin structure functions g 1 , g 2 and the generalized Gerasimov-Drell-Hearn sum rule in the small-Q 2 region are investigated by considering the resonance contributions based on nonrelativistic constituent quark model and on relativistic four-dimensional harmonic oscil
