Description
We investigate the form factors of the vector and axial-vector current between baryon states in the SU(3) chiral quark-soliton model. This relativistic model has only four parameters from which three are determined in the meson-sector whereas only one remains for the whole baryon-sector. One advantage of this model is therefore that various observables of all ground-state baryons can be investigated in the same scheme by having fixed only once these parameters. Results are given for the electromagnetic form factors of the Δ(1232) as well as for the magnetic moments of the decuplet baryons. Special interest is given to the Δ electric quadrupole form factor. We take linear 1/Nc and strange quark mass corrections into account. In addition we discuss also form factors of the semileptonic hyperon decays and properties of the pentaquark Θ+.
