# Oscillating Affleck-Dine condensate and its cosmological implications

## TL;DR

This paper investigates the post-inflation oscillations of the Affleck-Dine field, revealing their impact on baryon asymmetry and showing that certain leptogenesis models become viable due to these dynamics.

## Contribution

It provides a detailed analysis of Affleck-Dine field oscillations after inflation and their role in resolving baryogenesis issues in high-scale inflation models.

## Key findings

- Oscillations suppress baryon asymmetry in some models.
- Leptogenesis becomes feasible in high-scale inflation due to oscillation effects.
- Potential suppression of baryon asymmetry depends on superpotential form.

## Abstract

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). It is found that the Affleck-Dine leptogenesis in high-scale inflation, which suffers from serious gravitino overproduction, becomes workable owing to this effect.
