Photo-production of Nucleon Resonances and Nucleon Spin Structure Function in the Resonance Region
arXiv:hep-ph/0106225 · doi:10.1103/PhysRevC.65.015202
Abstract
The photo-production of nucleon resonances is calculated based on a chiral constituent quark model including both relativistic corrections H{rel} and two-body exchange currents, and it is shown that these effects play an important role. We also calculate the first moment of the nucleon spin structure function g1 (x,Q^2) in the resonance region, and obtain a sign-changing point around Q^2 ~ 0.27 {GeV}^2 for the proton.
