A combined framework of both expansions has been developed and applied for baryons with three light-quark-flavors. The small scale expansion of the combined approach is identified as the $\\xi$-expansion, in which the power counting of the expansions is linked according to $O(p)=O(1/N_c)=O(\\xi)$. The physical baryon masses as well as lattice QCD baryon masses for different quark mass masses are analyzed to $O(\\xi^3)$ in that framework. $\\sigma$ terms are addressed using the Feynman Hellmann t","authors_text":"Ishara P.
