de Sitter空间中守恒电荷的形成

Formation of conserved charge at the de Sitter space

V. V. Nikulin, S. G. Rubin, P. M. Petryakova

摘要:

本文考虑了一种新的机制,电荷积累在早期宇宙的理论与紧凑的额外的维度。额外空间度规在形成过程中发生的弛豫过程导致对称额外空间配置的建立。结果,与对称性相关的数的初始累积发生。我们证明了这种机制使用一个简单的例子,一个二维的苹果状额外的空间度量与$U(1)$对称性。这个机制的概念可以用来发展一个早期宇宙中重子或轻子数产生的模型。

英文摘要:

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.
