Update of the stranger story: The strange vector form factors of the nucleon in the SU(3) chiral quark-soliton model

The strange vector form factors are evaluated for $Q^2=0$ and $Q^2=1
\mbox{GeV}^2$ in the framework of the SU(3) chiral quark-soliton model (or semi-bosonized SU(3) Nambu-Jona-Lasinio model). The rotational $1\mathrm{/}{N}_c$ and $m_s$ corrections are taken into account up to linear order. The mean-square strange radius $⟨r^2{⟩}_s^{Sachs}=-0.35f{m}^2$ and the strange magnetic moment ${\mu }_s=-0.44{\mu }_N$ are obtained. The results are compared with several different models.
