Description
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∼1/2mp, mν∼0.12eV each flavor). We assume DE to be a self-interacting scalar field and use a standard Monte Carlo Markov Chain approach.
