%0 Journal Article %T The dark matter as a light gravitino %A Moultaka %A Gilbert %J High Energy Physics - Phenomenology %D 2007 %I %R 10.1063/1.2823771 %X We address the question of gravitino dark matter in the context of gauge mediated supersymmetry breaking models. A special emphasis is put on the role played by the MSSM singlet messenger in the case of SO(10) grand unification. %U http://arxiv.org/abs/0710.5121
