Inflation in minimal left-right symmetric model with spontaneous D-parity breaking
arXiv:0705.0068 · doi:10.1103/PhysRevD.77.023517
Abstract
We present a simplest inflationary scenario in the minimal left-right symmetric model with spontaneous D-parity breaking, which is a well motivated particle physics model for neutrino masses. This leads us to connect the observed anisotropies in the cosmic microwave background to the sub-eV neutrino masses. The baryon asymmetry via the leptogenesis route is also discussed briefly.
