Oscillating Affleck-Dine condensate and its cosmological implications

Understand

We study the dynamics of the Affleck-Dine field after inflation in more detail.

• After inflation, the Affleck-Dine field inevitably oscillates around the potential minimum.
• This oscillation is hard to decay and can cause accidental suppression of the consequential baryon asymmetry.
• This suppression is most effective for the model with non-renormalizable superpotential $W_{AD}\sim \Phi^4$ ($\Phi$: Affleck-Dine field).
