Revisiting the gravitino dark matter and baryon asymmetry from Q-ball
  decay in gauge mediation
  We reinvestigate the scenario that the amount of the baryons and the
gravitino dark matter is naturally explained by the decay of the Q balls in the
gauge-mediated SUSY breaking. Equipped by the more correct decay rates into
gravitinos and baryons recently derived, we find that the scenario with the
direct production of the gravitino dark matter from the Q-ball decay works
naturally.
