Abstract
The dark energy density of the universe is obtained from the Higgs potential by introducing a Higgsdependent neutrino mass. In the standard picture of electro-weak symmetry breaking the Higgs potential is V/ = (k/4)(/2 v2)2 and the Higgs field rolls down to the minima at h/i = v = 246.2 GeV and the net vacuum energy is zero. Now if the neutrino mass is a function of the Higgs field, then the vacuum expectation value of the Higgs is determined by maximizing the total pressure of the Higgs self interaction and the neutrino fluid P/ + Pm(m(/)) w.r.t /. The new minima h/i = v + rm shifts from the standard Higgs vev v by a small amount rm. The total pressure of the Higgs-neutrino coupled fluid P/(v + rm) + Pm(v + rm) = qK appears as the dark energy density of the universe. The magnitude of the dark energy is thus determined by to the neutrino mass and the Higgs potential.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
