| dc.description | In this talk we discuss the origin and nature of the dark matter in the Affleck-Dine (AD) baryogenesis. The AD baryogenesis via most of the flat directions predict formations of large Q-balls, and a great number of the lightest supersymmetric particles (LSPs) are produced nonthermally via the late-time decays of these Q-balls. In order to avoid the overclosure of the universe by these nonthermally produced LSPs, an LSP with a large pair-annihilation cross section, like Higgsino- or Wino-like neutralino, is required, instead of the standard Bino-like neutralino. This reveals new cosmologically interesting parameter regions in various SUSY breaking models, which have not attracted much attention so far. | |
