| Publication Abstract: | The chiral and 1/Nc expansions are combined in the description of low energy baryons. The combination furnishes a better behaved expansion, consequence of exactly eliminating large terms that violate the 1/Nc expansion and which are typical of formulations of BChPT where consistency with the large $N_c$ limit is disregarded. The improvements are particularly dramatic in the case of SU(3). The general framework is outlined and applications to the vector charges and axial couplings are presented. A discussion of Lattice QCD results with three quark flavors for axial couplings is presented. |
