Inhomogeneous baryogenesis, cosmic antimatter, and dark matter
A. D. Dolgov, M. Kawasaki, N. Kevlishvili
A model of inhomogeneous baryogenesis based on the Affleck and Dine mechanism is described. A simple coupling of the scalar baryon field to the inflaton allows for formation of ast…
Electron and Photon Energy Deposition in Universe
Toru Kanzaki, Masahiro Kawasaki
We consider energy deposition of high energy electrons and photons in universe. We carry out detailed calculations of fractions of the initial energy of the injected electron or ph…
Solving Cosmological Problems of Supersymmetric Axion Models in an Inflationary Universe
Masahiro Kawasaki, Kazunori Nakayama
We revisit inflationary cosmology of axion models in the light of recent developments on the inflaton decay in supergravity. We find that all the cosmological difficulties, includi…
Solving the cosmic lithium problems with primordial late-decaying particles
Daniel Cumberbatch, Kazuhide Ichikawa, Masahiro Kawasaki +3
We investigate the modifications to predictions for the abundances of light elements from standard Big-Bang nucleosynthesis when exotic late-decaying particles with lifetimes excee…
