Proton strangeness induced by instantons

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