Nw. Park, ELECTROMAGNETIC STRUCTURE OF THE SOLITON IN THE SU(3) NAMBU-JONA-LASINIO MODEL, Journal of the Korean Physical Society, 27(2), 1994, pp. 210-214
The electromagnetic form factors of the soliton are derived with the o
ne-quark loop approximation in the semi-bosonized SU(3) Nambu-Jona-Las
inio model in the collective formulation. Compared to the SU(2), there
are anomalous currents which are finite and are not regularized due t
o the imaginary part of the Euclidean effective action in addition to
the usual currents which are regularized. We evaluate the magnetic mom
ent for the octet baryons and find that the model without the boson lo
op and the vector mesons predicts low values generally. Also, relevant
problems are discussed.
