Strange and singlet form factors of the nucleon: Predictions for G0, A4, and HAPPEX-II experiments

Abstract

We investigate the strange and flavor-singlet electric and magnetic form factors of the nucleon within the framework of the SU(3) chiral quark-soliton model. Isospin symmetry is assumed and the symmetry-conserving SU(3) quantization is employed, rotational and strange quark mass corrections being included. For the experiments G0, A4, and HAPPEX-II we predict the quantities $G_E^0+\beta G_M^0$ and $G_E^{\mathrm{s}}+\beta G_M^{\mathrm{s}}$. The dependence of the results on the parameters of the model and the treatment of the Yukawa asymptotic behavior of the soliton are investigated.
