Abstract

If neutrino mass is a function of the Higgs potential then minimum of the total thermodynamic potential Ω\Omega (which is the Higgs potential minus the neutrino pressure) can shift from the standard electro-weak vev v=246.2v=246.2 GeV by a small amount which depends on the neutrino pressure. If the neutrino mass is a very steep function of the Higgs field then the equilibrium thermodynamic potential can act like the dark energy with ω1\omega \simeq -1. Choosing the neutrino mass as logarithmic function of the Higgs field and a heavy mass scale, we find that the correct magnitude of the cosmological density of the present universe ρλ(0.002eV)4\rho_\lambda \simeq (0.002 eV)^4 is obtained by choosing the heavy mass at the GUT scale.
