$\Omega_0 <1$ From Inflation

High Energy Physics - Phenomenology 2016-09-01 v1 Astrophysics

Abstract

An inflationary scenario that leads to Ω0<1\Omega _0<1 today is presented. An epoch of `old' inflation during which the smoothness and horizon problems are solved is followed by a shortened epoch of `new' inflation. Old inflation exits through the nucleation of a single bubble, leading to negative spatial curvature on slices of constant cosmic time. We calculate the spectrum of density perturbations in such a scenario.
