Baryon Spectroscopy and The X * Program at Jlab/CLAS. The Advantages of X * Experiments Complimentary to N* program For every N* and D , there is a X * Narrow width ( G ( X *) ~ 1/5 G (N*/ D )) Partial Wave Analysis far simpler Easy Identification: Missing Mass

Baryon Spectroscopy andThe X* Program at Jlab/CLAS The Advantages of X* Experiments Complimentary to N* program For every N* and D, there is a X* Narrow width (G(X*) ~ 1/5 G(N*/D)) Partial Wave Analysis far simpler Easy Identification: Missing Mass Invariant Mass (detached vertices) Isospin simplicity (I = ½) SU(3) octet and decuplet- no singlet Disadvantage: No S-channel, reduced production cross section
Forward Central The CLAS12 central detector with SVT Scintillator Counters, dt=50ps • Forward part of SVT, 6 layers, strips oriented +/-1.5 degree stereo angle, will improve the vertex determination and the resolution, linked to the forward DC • Central part, 3 double sided layers, will provide tracking of charged particles in the solenoid field Silicon Vertex Tracker, 150mm pitch, d=50mm 5T SC Solenoid Magnet
