Series: | IFT-UAM/CSIC -08-01 | Abstract: | We consider cosmological consequences of a heavy axino, decaying to the neutralino in R-parity conserving models. The importance and influence of the axino decay on the resultant abundance of neutralino dark matter depends on the lifetime and the energy density of axino. For a high reheating temperature after inflation, copiously produced axinos dominate the energy density of the universe and its decay produces a large amount of entropy. As a bonus, we obtain that the upper bound on the reheating temperature after inflation via gravitino decay can be moderated, because the entropy production by the axino decay more or less dilutes the gravitinos. | Description: | Submitted on 3 Jan 2008 (v1), last revised 19 Jun 2008 (this version, v2).-- 7 pages, 4 figures; references added, published version in Phys.
