Sterile neutrinos help reconcile the observational results of primordial gravitational waves from Planck and BICEP2
We show that involving a sterile neutrino species in the ΛCDM+r model can help relieve the tension about the tensor-to-scalar ratio r between the Planck temperature data and the BICEP2 B-mode polarization data. Such a model is called the ΛCDM+r+νs model in this paper. Compared to the ΛCDM+r model, t...
