Abstract
An analysis is presented of the ground state baryon's (N and \Delta) masses and axial couplings in the combined 1/Nc and chiral expansions. Renormalization and alternative power counting schemes are discussed to one loop (NNLO). An application is made to lattice QCD results for non-strange baryon masses and the nucleon axial coupling as functions of the pion mass. This work represents a brief summary of a more extensive analysis to be presented elsewhere.
