<div>Abstract:<br>
</div>
<div>Baryon Chiral Perturbation Theory (BChPT) and the 1/Nc expansion provide systematic frameworks for the strong interactions at low energy. 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 $B&N(B-expansion, in which the power counting of the expansions is linked according to O(p) = O(1/Nc) = O($B&N(B). Results obtained from applying the combined framework to baryon masses, sigma terms
and vector and axial-vector currents in SU(3) will be discussed.</div>
