Dark matter from Affleck-Dine baryogenesis
Alexander Kusenko (UCLA)
TL;DR
This paper explores how the fragmentation of the Affleck-Dine condensate into Q-balls could produce dark matter, linking its origin to baryogenesis and suggesting potential observable consequences.
Contribution
It proposes a novel mechanism where Q-ball formation from Affleck-Dine condensate explains dark matter's origin and its connection to baryonic matter.
Findings
Q-balls can be stable or unstable, affecting dark matter composition.
Dark matter may originate from decay of unstable Q-balls.
The model links baryogenesis with dark matter production.
Abstract
Fragmentation of the Affleck-Dine condensate into Q-balls could fill the Universe with dark matter either in the form of stable baryonic balls, or LSP produced from the decay of unstable Q-balls. The dark matter and the ordinary matter in the Universe may share the same origin.
