Decaying gravitino dark matter and an upper bound on the gluino mass
  We show that, if decaying gravitino dark matter is responsible for the PAMELA
and ATIC/PPB-BETS anomalies in the cosmic-ray electron and positron fluxes,
both a reheating temperature and a gluino mass are constrained from above. In
particular, the gluino mass is likely within the reach of LHC, if the observed
baryon asymmetry is explained by thermal leptogenesis scenario.
