Irgac2006 Dark Energy and the False Vacuum
نویسنده
چکیده
In this talk, I will present highlights of a recent model of dark energy and dark matter in which the present universe is " trapped " in a false vacuum described by the potential of an axion-like scalar field (the acceleron) which is related to a new strong interaction gauge sector, SU (2) Z , characterized by a scale Λ Z ∼ 3 × 10 −3 eV. This false vacuum model mimicks the ΛCDM scenario. In addition, there are several additional implications such as a new mechanism for leptogenesis coming from the decay of a " messenger " scalar field, as well as a new model of " low-scale " inflation whose inflaton is the " radial " partner of the acceleron.

Phenomenology of Hybrid Scenarios of Neutrino Dark Energy
We study the phenomenology of hybrid scenarios of neutrino dark energy, where in addition to a so-called Mass Varying Neutrino (MaVaN) sector a cosmological constant (from a false vacuum) is driving the accelerated expansion of the universe today. For general power law potentials we calculate the effective equation of state parameter weff (z) in terms of the neutrino mass scale. Due to the inte...
متن کاملFalse Vacuum in the Supersymmetric Mass Varying Neutrinos Model
We present detailed analyses of the vacuum structure of the scalar potential in a supersymmetric Mass Varying Neutrinos model. The observed dark energy density is identified with false vacuum energy and the dark energy scale of order (10eV) is understood by gravitationally suppressed supersymmetry breaking scale, F (TeV)/MPl, in the model. The vacuum expectation values of sneutrinos should be t...
متن کاملVacuum Energy: Myths and Reality
We discuss the main myths related to the vacuum energy and cosmological constant, such as: “unbearable lightness of space-time”; the dominating contribution of zero point energy of quantum fields to the vacuum energy; non-zero vacuum energy of the false vacuum; dependence of the vacuum energy on the overall shift of energy; the absolute value of energy only has significance for gravity; the vac...
متن کاملThe Cosmological Constant, False Vacua, and Axions
It is suggested that the true ground state of the world has exactly vanishing vacuum energy and that the cosmological constant that seems to have been observed is due to our region of the universe being stuck in a false vacuum, whose energy is split from the true vacuum by non-renormalizable operators that are suppressed by powers of the Planck scale. It is shown that conventional invisible axi...

A supersymmetric hybrid potential model with low energy supersymmetry breaking scale (MS ∼ 1 − 10Tev) is presented for both dark matter and dark energy. Cold dark matter is associated with a light modulus field (∼ 10−100Mev) undergoing coherent oscillations around a saddle point false vacuum with the presently observed energy density (ρ0 ∼ 10 eV ). The latter is generated by its coupling to a l...
