Scientific paper

One of the biggest mystery of the recent observation of cosmic microwave background anisotropies by the boomerang team is insignificance of the second acoustic peak in the angular power spectrum. It is very difficult to explain such a low amplitude without assuming the higher baryon density than predicted by the Big Bang Nucleosynthesis (BBN). Employing the double inflation model in supergravity, we show that the density fluctuations produced by this inflation model can produce a sufficient low second acoustic peak with the standard value of the baryon density from BBN. It is shown that these density fluctuations are also consistent with the observations of cluster abundances and galaxy distributions.
