Abstract
After a period of inflationary expansion, the Universe reheated and reached full thermal equilibrium at the reheating temperature. In this talk, based on the paper, arXiv:0710.3349, we point out that, in the context of effective low-energy supersymmetric models, LHC measurements may allow one to determine reheating temperature as a function of the mass of the dark matter particle assumed to be either an axino or a gravitino. An upper bound on their mass and on the reheating temperature may also be derived.
