Title : Dark radiation : another dark component ?

Abstract : Recent observations of the CMB anisotropy and primordial helium abundance
show a bit preference for Neff > 3, where Neff is the effective number of neutrino species.
This may indicate the existence of "dark" radiation, which consist of light non-interacting particles other than neutrinos.
We construct models explaining dark radiation and discuss their experimental/observational signatures.
