Scientific paper

A supersymmetric hybrid potential model with low energy supersymmetry breaking scale (MS ~ 1 - 10Tev) is presented for both dark matter and dark energy. Cold dark matter is associated with a light modulus field (~ 10 - 100Mev) undergoing coherent oscillations around a saddle point false vacuum with the presently observed energy density (ρ0 ~ 10-12eV4). The latter is generated by its coupling to a light dark energy scalar field (~ 10-18eV) which is trapped at the origin ("locked quintessence"). Through naturally attained initial conditions the model is consistent with cosmic coincidence reproducing LCDM cosmology. An exit from the cosmic acceleration phase is estimated to occur within some eight Hubble times.
