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\(\otimes U(1)_{\mathrm{B}\mbox{--}\mathrm{L}}\). In order to obtain a varying neutrino mass, we make an assumption that a soft mass of \(\tilde{Z'}_{\mathrm{BL}}\) 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.
