Baryogenesis, Dark Matter, and Flavor Structure in Non-thermal Moduli Cosmology

Understand

The appearance of scalar/moduli fields in the early universe, as motivated by string theory, naturally leads to non-thermal "moduli cosmology".

• Such cosmology provides a consistent framework where the generation of radiation, baryons, and dark matter can occur while maintaining successful Big Bang Nucleosynthesis and avoiding the cosmological moduli problem.
• We present a relatively economical construction with moduli cosmology, building on a variety of string-inspired components (e.g.
• supersymmetry, discrete symmetries, Green-Schwarz anomaly cancellation).
