摘要：

In this paper, 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 Lambda(Z) similar to 3 x 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.
