24 Dec 2004 | | Journal: | Int.J.Mod.Phys. A20 (2005) 1568-1574 | | Subject: | nucl-ex | | Abstract: | At ELSA interesting results on baryon resonances have been obtained by the CB-ELSA, the CBELSA/TAPS and the SAPHIR collaborations. New resonances were found, in particular a new $
m D_{15}(2070)$ decaying into $peta$, was recently observed by the CB-ELSA experiment. The availability of a polarized beam and a polarized target did allow to measure the GDH sum rule up to 2.9 GeV. In the future double polarization experiments will be performed using the Crystal Barrel detector together with new forward detector components. These polarization observables will provide important additional information for the partial wave analyses performed to extract the contributing resonances and their parameters from the data. | | Source: | arXiv, nucl-ex/0501024 | | Services: | Forum | Review | PDF | Favorites | |
