Title: Electromagnetic properties of the {delta}(1232) and decuplet baryons in the self-consistent SU(3) chiral quark-soliton model

Abstract

We examine the electromagnetic properties of the {delta}(1232) resonance within the self-consistent chiral quark-soliton model. In particular, we present the {delta} form factors of the vector-current G{sub E0}(Q{sup 2}), G{sub E2}(Q{sup 2}), and G{sub M1}(Q{sup 2}) for a momentum-transfer range of 0{<=}Q{sup 2}{<=}1 GeV{sup 2}. We apply the symmetry-conserving quantization of the soliton and take 1/N{sub c} rotational corrections into account. Values for the magnetic moments of all decuplet baryons as well as for the N-{delta} transition are given. Special attention is also given to the electric quadrupole moment of the {delta}.
