Sažetak
We report on a calculation of the dilute instanton liquid contribution to the strangeness in the proton. Specifically, we express the proton matrix elements of strange-quark operators in terms of a model valence nucleon state and the strangeness producing interactions. This enables us to evaluate the strangeness in different Lorentz channels in the same way. We find that in the context of the MIT bag model only the scalar strangeness is induced by the random instanton liquid. We discuss these results in the light of the recent experiments.
