MSSM Higgses as the source of reheating and all matter
Kari Enqvist, Shinta Kasuya, Anupam Mazumdar
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 Hu and Hd, which acquires large amplitude by virtue of quantum fluctuations during inflation. The reheat temperature is TRH 109 GeV so that there is no gravitino problem. We find a spectral index ns≈ 1 with a very weak dependence on the Higgs potential.
