We analyse the baryon mass spectrum in a framework which combines the 1/Nc expansion with chiral perturbation theory. Meson loop contributions involving the full SU(3) octet of pseudoscalar Goldstone bosons are evaluated, and the influence of explicit chiral and flavor symmetry breaking by non-zero and unequal quark masses is investigated. We also discuss sigma terms and the strangeness contribution to the nucleon mass.

  1. The Baryon-Baryon Interaction in the Large-$N_c$ Limit

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A large-N_c analysis of the chiral baryon-baryon potential cuts the leading-order contact couplings from fifteen to three and fixes F/D=2/3 and C/D=2.
