Evolutionary effects in one-bubble open inflation for string landscape |
|
Abstract |
The open inflationary scenario is attractinga renewed interest in the context of string landscape. Since there are a large number of metastable de Sitter vacua in string landscape, tunneling transitions to lower metastable vacua through the bubble nucleation occur quite naturally, which leads to a natural realization of open inflation. Although the deviation of $\Omega_{0}$ from unity is small by the observational bound, the effect of this small deviation on the CMB anisotropies might be significant. We argued that the effect of the small deviation of the density parameter on the large angle CMB anisotropies may be significant for tensor-type perturbationin open inflation scenario. |
