Résumé:

We address the question of dark matter in the context of gauge mediated supersymmetry breaking models. In contrast with mSUGRA scenarios, the messenger of the susy breaking to the visible sector can play an important role allowing a relic gravitino in the similar to keV to 10 MeV mass range to account for the cold dark matter in the Universe.
