Abstract:
We argue directly from Witten's analysis of large NcN_c baryons that the structure of the ss-wave low-spin baryon states in QCD becomes spin-independent as NcN_c\rightarrow\infty. This property leads to SU(6)SU(6)-like behavior of static matrix elements, such as the axial-vector current matrix elements recently studied by Dashen, Manohar and Jenkins. Our analysis suggests a method for applying large NcN_c results for Nc=3N_c=3, even though the baryon states for large NcN_c are very different.
