Electromagnetic form factors of the SU(3) octet baryons in the semibosonized SU(3) Nambu–Jona-Lasinio model

Abstract

The electromagnetic form factors of the SU(3) octet baryons are investigated in the semibosonized SU(3) Nambu--Jona-Lasinio model (chiral quark-soliton model). The rotational 1/${\mathit{N}}_{\mathit{c}}$ and strange quark mass corrections in linear order are taken into account. The electromagnetic charge radii of the nucleon and magnetic moments are also evaluated. It turns out that the model is in remarkably good agreement with the experimental data. \textcopyright{} 1996 The American Physical Society.
