Abstract (EN):
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 G0E + betaG0M and GsE + betaGsM. The dependence of the results on the parameters of the model and the treatment of the Yukawa asymptotic behavior of the soliton are
