Bimodal/Schizophrenic Neutrino As a Bridge between Inflation and Dark Energy

Abstract

We consider the possibility to combine inflection point inflation and growing neutrino dark energy in a particular setup of bimodal/schizophrenic neutrino model in the framework of MSSM$\otimes U(1{)}_{B-L}$. In order to obtain a varying neutrino mass, we make an assumption that a soft mass of ${\widetilde{Z^{\prime }}}_{BL}$ depends on a scalar field which plays the role of a cosmon field. We also investigate the possible effects of the cosmon field in the early universe such as modulated reheating and found that the induced density perturbation is negligible.
