Negative cosmological constant in the dark sector?
Rodrigo Calderón, Radouane Gannouji, Benjamin L'Huillier +1
We consider the possibility that the dark sector of our Universe contains a negative cosmological constant dubbed . For such models to be viable, the dark sector should contain…
Direct Detection of Primordial Gravitational Waves in a BSI Inflationary Model
D. Polarski
We investigate the possibility for a direct detection by future space interferometers of the stochastic gravitational wave (GW) background generated during the inflationary stage i…
CDM models with a BSI steplike primordial spectrum and a cosmological constant
J. Lesgourgues, D. Polarski, A. A. Starobinsky
A class of spatially-flat models with cold dark matter (CDM), a cosmological constant and a broken-scale-invariant (BSI) steplike primordial (initial) spectrum of adiabatic perturb…
Confrontation of Double-Inflationary Models with Observations
P. Peter, D. Polarski, A. A. Starobinsky
We consider double-inflationary models with two noninteracting scalar fields, a light scalar field with potential and a heavy scalar field with…
