Abstract

We allow simultaneously for a CDM-DE coupling and non-zero neutrino masses and find that significant coupling and neutrino mass are (slightly) statistically favoured in respect to a cosmology with no coupling and negligible neutrino mass (our best fits are: C ∼ 1 / 2 m p, m ν ∼ 0.12 eV each flavor). We assume DE to be a self-interacting scalar field and use a standard Monte Carlo Markov Chain approach. © 2009 Elsevier B.V. All rights reserved.
