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 MSSM flat direction condensate involving the Higgses HuH_u and HdH_d, which acquires large amplitude by virtue of quantum fluctuations during inflation. The reheat temperature is TRH109T_{RH} \lesssim 10^9 GeV so that there is no gravitino problem. We find a spectral index ns1n_s\approx 1 with a very weak dependence on the Higgs potential.
