Abstract

After a period of inflationary expansion, the Universe reheated and reached full thermal equilibrium at the reheating temperature TR. In this talk, based on [1], we point out that, in the context of effective low-energy supersymmetric models, LHC measurements may allow one to determine TR 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 TR may also be derived. [ABSTRACT FROM AUTHOR]
