(Seattle University and University of Washington)
Both perturbative and non-perturbative mechanisms contribute to strangeness in the proton sea. We have developed a hybrid model in which non-perturbative contributions are calculated in a meson cloud model which expands the proton in terms of meson-baryon states, and perturbative contributions are calculated in a statistical model which expands the proton in terms of quark-gluon states. The perturbative contributions are represented in the parton distributions of the ``bare'' hadrons in the meson cloud. We compare our results to the recent experimental data of ATLAS and HERMES.
