Observational constraints on the massive neutrinos induced late-time cosmic acceleration

We study a scenario based upon a mass-less $\lambda {\varphi }^4$ theory coupled to massive neutrino matter with $Z_2$ symmetry using a conformal coupling, $A(\varphi )=1-\alpha {\varphi }^2/2M_{pl}^2;\alpha =M_{pl}^2/M^2$…
