Baryon Isocurvature Scenario in Inflationary Cosmology: A Particle Physics Model and Its Astrophysical Implications
Abstract
A phenomenological model to produce isocurvature baryonnumber fluctuations is proposed in the framework of inflationary cosmology. The resulting spectrum of density fluctuation is very different from the conventional HarrisonZel'dovich shape. The model, with the parameters satisfying several requirements from particle physics and cosmology, provides an appropriate initial condition for the minimal baryon isocurvature scenario of galaxy formation discussed by Peebles.
