 | Gondolo, Paolo | Effect of a late decaying scalar on the neutralino relic density | If the energy density of the Universe before nucleosynthesis is dominated by a scalar field Ø that decays and reheats the plasma to a temperature TRH smaller than the standard neutralino freeze-out temperature, the neutralino relic density differs from its standard value. In this case, the relic de... | Neutralinos; Relic density; Reheating temperature | 2006-10 |

 | Gondolo, Paolo | Neutralino with the right cold dark matter abundance in (almost) any supersymmetric model | We consider nonstandard cosmological models in which the late decay of a scalar field Ø reheats the Universe to a low reheating temperature, between 5 MeV and the standard freeze-out temperature of neutralinos of mass mx. We point out that in these models all neutralinos with standard density Ώstd... | Neutralinos; Reheating temperature | 2006-07 |
