Photoproduction of Cascade baryons

Yongseok Oh (UGA) H. Haberzettl (GWU) K. Nakayama (UGA) nucl-th/0605169. Photoproduction of Cascade baryons. If all the particles can be classified as SU(3) flavor octet or decuplet, N( X ) = N(N*) + N( D *) So far, only a dozen or so of X have been identified.

Photoproduction of the S (1385) resonance at LEPS

Photoproduction of the S (1385) resonance at LEPS. K. Hicks & D. Keller, Ohio U. LEPS Collaboration Meeting May 1, 2008. Motivation - 1. Very few data exist for the S (1385). It is an important part of the decuplet group. It is difficult to disentangle from the L (1405).
