Cascade Spectroscopy and Recent Ξ* Photo-production Results from CLAS

Doubly-strange baryon resonances provide new insights into baryon structure. The standard QCD Lagrangian implies that for every N* and Δ* resonance, there should be a corresponding Ξ(cascade resonance). This is due to the flavor symmetry of the strong force. Therefore, one can investigate baryon structure by observing aspects of the doubly-strange baryons like regularities such as parity doublets. At energies above approximately 1.5 GeV, the light-quark baryon resonances are broad and overlap while the cascades in this range are narrow and therefore more readily observed. An overview of the world cascade spectrum and a comparison to the lighter baryon spectra will be presented. Recent results from an on-going analysis from the G12 (5.4 GeV) photo-production experiment using the CLAS detector at JLab will be highlighted.
