Light baryon magnetic moments and N -> Delta gamma transition in a Lorentz covariant chiral quark approach

Abstract

We calculate magnetic moments of light baryons and N -> Delta gamma transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound states of constituent quarks dressed by a cloud of pseudoscalar mesons.
