| Title: |
Indirect Signatures of Gravitino Dark Matter |
| Abstract: |
Supersymmetric models provide very interesting candidates for
the dark matter of the Universe. The nature of the dark matter is
severely
constrained by the requirement of a consistent thermal history of the
Universe with successful Big Bang nucleosynthesis and successful
baryogenesis. In this talk we review the constraints on the nature of
the
supersymmetric dark matter and we argue that all these constraints point
to a scenario with gravitino dark matter and a small amount of R-parity
violation. We also discuss possible signatures of this scenario at gamma
ray observatories, antimatter experiments and colliders.
