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.

    hep-ph 2024-12 conditional novelty 6.0 of 10

    Q-ball perturbation theory is shown to remain valid for wavepacket amplitudes below about 10^-2 of the Q-ball background, and the analysis is extended to two-field FLS Q-balls.
