Title: $S U (3)$ vector currents in baryon chiral perturbation theory combined with the $1 / N_{c}$ expansion

Abstract

Baryon chiral perturbation theory (BChPT) combined with the $1 / N_{c}$ expansion is applied to the $S U (3)$ vector currents. In terms of the $ξ$ power counting linking the low-energy and $1 / N_{c}$ expansions according to $O (ξ) = O (p) = O (1 / N_{c})$ , the study is carried out to next-to-next-to-leading order, and it includes $S U (3)$ breaking corrections to the $| Δ S | = 1$ vector charges, charge radii, and magnetic moments and radii. The results are obtained for generic $N_{c}$ , allowing for investigating the various scalings in $N_{c}$ .
