Outline of Final Research Achievements

We have considered axions and supersymmetric particles as promising candidates for dark matter which acquire fluctuations during inflation. We have studied cosmological effects of the fluctuations on cosmic microwave background and obtained stringent constraints on particle physics models. We have also shown that co-genesis of baryon number and dark matter is possible in Affleck-Dine mechanism which accounts for matter and anti-matter asymmetry of the universe in supersymmetric theories. Furthermore we have found that primordial black holes are a good candidate for dark matter and built a inflation model which can produce an appropriate amount of primordial black holes.
