In this paper, we discuss the mechanism for generating the lepton/baryon number and its subsequent conservation based on extra-dimensional evolution. The internal angular momentum of extra space is related to the lepton/baryon charge. Extra space metric is assumed to be initially asymmetric. Symmetries appear during inflation due to an increase in entropy. Using the multidimensional field toy model, we show that internal angular momentum can accumulate in fermions, which could explain the lepton/baryon asymmetry of the universe.

用 Kaluza-Klein 额外维度表示的宇宙重子/轻子不对称性

在本文中，我们讨论了轻子/重子数的产生机制及其基于超维演化的后续守恒。额外空间的内部角动量与轻子/重子电荷有关。假设额外空间度量最初是不对称的。由于熵的增加，在膨胀过程中会出现对称性。使用多维场玩具模型，我们证明了内部角动量可以在费米子中积累，这可以解释宇宙的轻子/重子不对称性。
