Most of model considerations of the hidden nucleon strangeness, as well assome preliminary experimental evidence, led to the expectations of relativelysizeable strange vector form factors of the proton. For example, it seemed thatthe contribution of the fluctuating strange quark-antiquark pairs accounts foras much as one tenth of the proton's magnetic moment. By the same token, baryonmodels which failed to produce the "vector strangeness" of the nucleon seemeddisfavored. Recently, however, more accurate measurements and moresophisticated data analysis, as well as lattice simulations, revealed that theform factors associated with the vector strangeness of the nucleon are muchsmaller than thought previously; in fact, due to the experimentaluncertainties, the measured strange vector-current proton form factors may beconsistent with zero. In the light of that, we re-asses the merit of the baryonmodels leading to little or no vector strangeness of the nucleon. It is done onthe concrete example of the baryon model which essentially amounts to the MITbag enriched by the diluted instanton liquid.

Unexpectedly small empirical vector strangeness of nucleons realized in a baryon model
