It has recently been proposed that the production of long wavelength Higgsand gauge configurations via parametric resonance at the end of inflation maygive rise to the required baryon asymmetry at the electroweak scale. We showthat the stability of the inflaton oscillations, long after the production ofHiggs modes, keeps driving the sphaleron transitions, which then becomestrongly correlated to the inflaton oscillations. In models where theCP-violation operator is related to time variations of the Higgs field, thesecorrelations immediately lead to an efficient generation of baryons that arenot washed out after the resonance.Comment: 5 pages, RevTeX, 8 figures, included with eps
