20 Jun 2001 | | Journal: | Phys.Rev. C65 (2002) 015202 | | Subject: | hep-ph nucl-th | | Affiliation: | Universidad Federico Santa Maria, Chile, and Southwest Jiaotong University, China) and Ivan Schmidt (Universidad Federico Santa Maria, Chile | | 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. | | Source: | arXiv, hep-ph/0106225 | | Services: | Forum | Review | PDF | Favorites | |
