Low-scale inflation in a model of dark energy and dark matter

We present a complete particle physics model that explains three major problems of modern cosmology: inflation, dark matter and dark energy, and also gives a mechanism for leptogenesis. The model has a new gauge group $SU(2)_Z$ that grows strong at a scale $\Lambda\sim 10^{-3}$ eV. We focus on the inflationary aspects of the model. Inflation occurs with a Coleman-Weinberg potential at a low scale, down to \sim 6\times 10^5\gev, being compatible with observational data.Comment: 5 two-column pages, RevTex4; two reference added and minor changes made in the text; published in JCA

Dark Energy and the False Vacuum

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 {\em 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 $\Lambda_Z \sim 3 \times 10^{-3} eV$. This false vacuum model mimicks the $\Lambda CDM$ 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.Comment: 6 pages.
