Title: Baryon chiral perturbation theory combined with the 1 / N c expansion in SU(3): Framework

Baryon Chiral Perturbation Theory combined with the $$1/N_c$$ expansion is implemented for three flavors. Here, Baryon masses, vector charges and axial vector couplings are studied to one-loop and organized according to the $$\xi$$-expansion, in which the $$1/N_c$$ and the low energy power countings are linked according to $$1/N_c={\cal{O}}(\xi)={\cal{O}}(p)$$. The renormalization to $${\cal{O}}(\xi^3)$$ necessary for the mentioned observables is provided, along with applications to the baryon masses and axial couplings as obtained in lattice QCD calculations.
