Dark Matter Gravitinos and Baryons via Q-ball decay in the Gauge-Mediated MSSM
Francesca Doddato, John McDonald
We show that late Q-ball decay in the MSSM with gauge-mediated SUSY breaking can provide a natural source of non-thermal NLSPs which subsequently decay to gravitino dark matter wit…
New Q-ball Solutions in Gauge-Mediation, Affleck-Dine Baryogenesis and Gravitino Dark Matter
Francesca Doddato, John McDonald
Affleck-Dine (AD) baryogenesis along a d=6 flat direction in gauge-mediated supersymmetry-breaking (GMSB) models can produce unstable Q-balls which naturally have field strength si…
Comment on "Gravitino Dark Matter and Baryon Asymmetry from Q-ball Decay in Gauge Mediation (arXiv:1107.0403)"
Francesca Doddato, John McDonald
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…
Affleck-Dine Baryogenesis, Condensate Fragmentation and Gravitino Dark Matter in Gauge-Mediation with a Large Messenger Mass
Francesca Doddato, John McDonald
We study the conditions for successful Affleck-Dine baryogenesis and the origin of gravitino dark matter in GMSB models. AD baryogenesis in GMSB models is ruled out by neutron star…
