27 Dec 2003 | Journal: | Nucl.Phys. A737 (2004) 248-252 | Subject: | nucl-th | Affiliation: | NTU, Taiwan), S.S. Kamalov (JINR, Dubna), D. Drechsel and L. Tiator (Mainz, Germany | Abstract: | We show that, within a meson-exchange dynamical model describing well most of the existing pion electromagnetic production data up to the second resonance region, one is also able to obtain a good agreement with the pi^0 photo- and electroproduction data near threshold. In the case of pi^0 production, the effects of final state interaction in the threshold region are nearly saturated by single charge exchange rescattering. This indicates that in ChPT, it might be sufficient to carry out the calculation just up to one-loop diagrams for threshold neutral pion production. | Source: | arXiv, nucl-th/0312117 | Services: | Forum | Review | PDF | Favorites |
