Description

We use a version of the meson cloud model, including the kaon and the 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 the forward G0 electron-proton scattering experiment. We conclude that it is very important to determine experimentally the electric and magnetic strange form factors, and not only the combination GEs+η GMs, if one does really intend to understand the strangeness of the nucleon
