19 Jan 2007 | | Abstract: | A Regge-plus-resonance (RPR) description of the p(gamma,K)Y and p(e,e’K)Y processes (Y = Lambda, Sigma^{0,+}) is presented. The proposed reaction amplitude consists of Regge-trajectory exchanges in the t channel, supplemented with a limited selection of s-channel resonance diagrams. The RPR framework contains a considerably smaller number of free parameters than a typical effective-Lagrangian model. Nevertheless, it provides an acceptable overall description of the photo- and electroproduction observables over an extensive photon energy range. It is shown that the electroproduction response functions and polarization observables are particularly useful for fine-tuning both the background and resonance parameters. | | Source: | arXiv, nucl-th/0701057 | | Services: | Forum | Review | PDF | Favorites | |
