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…
