Abstract

The AMS-02 collaboration has recently reported an excess of cosmic-ray positron fractions, which is consistent with previous results at the PAMELA experiment. The result indicates the existence of new physics phenomena to provide the origin of the energetic cosmic-ray positron. We pursue the possibility that the enhancement of the positron fraction is due to decays of gravitino dark matter. We discuss that such a scenario viably fits into the models in which the soft SUSY breaking parameters emerge dominantly from gauge-mediation mechanism with superparticle masses of around 10 TeV. Our scenario is compatible with the 126 GeV Higgs boson, negative results from searches for SUSY particles, and non-observation of anomalous flavor-changing processes. We also point out that the scenario will be tested in near future by measuring the electric dipole moment of the electron and the lepton flavor violating decay of the muon.
