Meson cloud and nucleon strangeness: An update

Abstract.

We use a version of the meson cloud model, including kaon, κ and K* contributions, to estimate the electric and magnetic strange form factors of the nucleon. We compare our results with the recent measurements of the strange-quark contribution to parity-violating asymmetries in electron-proton scattering experiments.
