    Baryon chiral perturbation theory combined with the 1/Nc expansion is implemented for three flavors. Baryon masses, vector charges and axial vector couplings are studied to one-loop and organized according to the ξ-expansion, in which the 1/Nc and the low-energy power countings are linked according to 1/Nc=O(ξ)=O(p). The renormalization to O(ξ3) necessary for the mentioned observables is provided, along with applications to the baryon masses and axial couplings as obtained in lattice QCD calculations.
