3 Feb 2004 | Journal: | Phys.Lett. A323 (2004) 182-189 | Subject: | gr-qc | Abstract: | We show that the non-perturbative vacuum structure associated with neutrino mixing leads to a non-zero contribution to the value of the cosmological constant. Such a contribution comes from the specific nature of the mixing phenomenon. Its origin is completely different from the one of the ordinary contribution of a massive spinor field. We estimate this neutrino mixing contribution by using the natural cut--off appearing in the quantum field theory formalism for neutrino mixing and oscillation. | Source: | arXiv, gr-qc/0402013 | Services: | Forum | Review | PDF | Favorites |
