Dark matter in axino-gravitino cosmology.
It is suggested that the axino mass in the 1 MeV region and gravitino mass in the eV region can provide an axino lifetime of order of the time of photon decoupling. In this case, some undecayed axinos act like cold dark matters and some axino decay products (gravitinos and hot axions) act like hot dark matters at the time of galaxy formation. The cosmological constant problem and the dark matte...
متن کاملSolving the Gravitino Problem by Axino
In a large class of supersymmetric (SUSY) axion model the mass of axino ã (a fermionic superpartner of the axion) is predicted as mã ∼ O(1) keV. Thus, the axino is the lightest SUSY particle (LSP). We pointed out that such a light axino provides a natural solution to the gravitino problem, if the gravitino is the next LSP. We derive a constraint on the reheating temperature TR of inflation, TR ...
متن کاملDetermining Reheating Temperature at Colliders with Axino or Gravitino Dark Matter
After a period of inflationary expansion, the Universe reheated and reached full thermal equilibrium at the reheating temperature TR. In this work 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 thei...
متن کاملDetermining Reheating Temperature at LHC with Axino or Gravitino Dark Matter
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 uppe...
متن کاملCollider Signatures of Axino and Gravitino Dark Matter
The axino and the gravitino are extremely weakly interacting candidates for the lightest supersymmetric particle (LSP). We demonstrate that either of them could provide the right amount of cold dark matter. Assuming that a charged slepton is the next-to-lightest supersymmetric particle (NLSP), we discuss how NLSP decays into the axino/gravitino LSP can provide evidence for axino/gravitino dark ...
