DARK MATTER CASTS LIGHT ON THE EARLY UNIVERSE

Dark matter casts light on the early Universe

Abstract We show how knowledge of the cold dark matter (CDM) density can be used, in conjunction with measurements of the parameters of a scenario for beyond the Standard Model (BSM) physics, to provide information Easter Kit about the evolution of the Universe before Big Bang Nucleosynthesis (BBN).As examples of non-standard evolution, we consider
