Abstract

The article considers a new mechanism of charge accumulation in the early Universe in theories with compact extra dimensions. The relaxation processes in the extra space metric that take place during its formation lead to the establishment of symmetrical extra space configuration. As a result, the initial accumulation of the number associated with the symmetry occurs. We demonstrate this mechanism using a simple example of a two-dimensional apple-like extra space metric with U ( 1 ) -symmetry. The conceptual idea of the mechanism can be used to develop a model for the production of the baryon or lepton number in the early Universe.
Keywords: symmetry breaking; baryon asymmetry; lepton asymmetry; baryon number; compact extra dimensions; extra space formation; apple-like extra space symmetry breaking; baryon asymmetry; lepton asymmetry; baryon number; compact extra dimensions; extra space formation; apple-like extra space
