Abstract
Non-strange members of the 70-plet baryons are analyzed within Large Nc QCD. The Large Nc approach is used as an effective theory to simultaneously fit the masses and decays with corrections up to O(1/Nc). Values of the mixing angles for the S=1/2 and S=3/2 nucleon mass eigenstates are obtained. The observed effective operator hierarchy is consistent with the previous studies conducted in this sector and improved results are obtained.
