Abstract

Description

We investigate whether the Affleck-Dine mechanism can produce sufficient baryon number of the universe in the gauge-mediated SUSY breaking models, while evading the cosmological moduli problem by late-time entropy production. We find that the Q-ball formation makes the scenario difficult, irrespective of the detail mechanism of the entropy production.
