论文摘要
我们开发了一种新的机制，用于在类似Kaluza-Klein的理论中在早期宇宙中积累保守数字的积累。早期宇宙中存在的原始额外空间扰动的放松导致建立了对称的最终状态和杀戮载体的出现。结果，与对称相关的数字的初始非零值发生在通货膨胀之后。我们在二维苹果般的额外空间的玩具模型上展示了这个概念性的想法，该模型与U（1）对称性。这种机制自然出现在Kaluza-klein理论中，可用于解释观察到的宇宙学重子不对称。
We develop a new mechanism for the accumulation of conserved numbers in the early Universe in Kaluza-Klein-like theories. The relaxation of the primordial extra space perturbations existing in the early Universe leads to the establishment of a symmetric final state and the appearance of Killing vectors. As a result, the initial non-zero value of symmetry associated numbers occurs after the inflation. We show this conceptual idea on a toy model of 2-dimensional apple-like extra space with U(1) symmetry. This mechanism naturally arises in the Kaluza-Klein theories and can be used to explain the observed cosmological baryon asymmetry.
