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

Abstract

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.
