Abstract

We consider the possibility that the dark energy responsible for inflation is deposited into extra dimensions outside of our observable Universe. Reheating and all matter can then be obtained from the minimal supersymmetric standard model flat direction condensate involving the Higgs bosons H_u and H_d, which acquires large amplitude by virtue of quantum fluctuations during inflation. The reheat temperature is T_RH\ensuremath\lesssim10⁹ GeV so that there is no gravitino problem. We find a spectral index n_s\ensuremath≈1 with a very weak dependence on the Higgs potential.
