Do WMAP data favor neutrino mass and a coupling between Cold Dark Matter and Dark Energy?

Do WMAP data favor neutrino mass and a coupling between Cold Dark Matter and Dark Energy?

We fit WMAP5 and related data by allowing for a CDM--DE coupling and non--zero neutrino masses, simultaneously. We find a significant correlation between these parameters, so that simultaneous higher coupling and \nu--masses are allowed. Furthermore, models with a significant coupling and \nu--mass are statistically favoured in respect to a cosmology …
