## Operator analysis of L=1 baryon masses in large N{sub c} QCD

Description:
The authors consider in detail the mass operator analysis for the nonstrange L=1 excited baryons in large N{sub c} QCD. They present a straightforward procedure for constructing the large N{sub c} baryon wavefunctions, and provide complete analytic expressions for the matrix elements of all the independent isosinglet mass operators. They discuss the relationship between the old-fashioned operator analyses based on nonrelativistic SU(6) symmetry and the modern large N{sub c} approach, which has a firmer theoretical foundation. They then suggest a possible dynamical interpretation for the subset of operators preferred strongly by the data.
