Description
Supersymmetric extensions of the Standard Modell with small R-parity and lepton number breaking naturally yield a consistent cosmology incorporating primordial nucleosynthesis, leptogenesis, and gravitino dark matter. Since the gravitino is no longer stable, its highly supressed decays should lead to characteristic signatures in high-energy cosmic rays. This talk examines the implications of constraints on gravitino lifetime from recent astrophysical data for the decays of the next-to-lightest superparticle (NLSP) at the LHC.
