Comment on "Gravitino Dark Matter and Baryon Asymmetry from Q-ball Decay in Gauge Mediation (arXiv:1107.0403)"

Abstract

We comment on a statement made in arXiv:1107.0403, which implies that the model of gravitino dark matter from Q-ball decay we presented in arXiv:1101.5328 is generally ruled out by the effect of NLSP decay on BBN. We explain why this statement is incorrect.
