Abstract

The strange vector form factors are evaluated for Q²=0 and Q²=1 GeV² in the framework of the SU(3) chiral quark-soliton model (or semi-bosonized SU(3) Nambu-Jona-Lasinio model). The rotational 1/N_c and m_s corrections are taken into account up to linear order. The mean-square strange radius ⟨ r²⟩^Sachs_s=-0.35 fm² and the strange magnetic moment μ_s = -0.44 μ_N are obtained. The results are compared with several different models.
