17 Nov 2006 | Abstract: | We estimate the coupling of K* vector meson to the N-->Theta+ transition employing the unitary simmetry, vector meson dominance, and results of the GRAAL Collaboration on the eta photoproduction off the neutron. Our small numerical value confirms that the CLAS Collaboration null results do not contradict to theoretical expectations for the Theta-production. We also estimate the K*-coupling for the N-->Sigma* excitation, with Sigma* being the Sigma-like antidecuplet partner of the Theta+ baryon. | Source: | arXiv, hep-ph/0611238 | Services: | Forum | Review | PDF | Favorites |
