Cosmological baryon/lepton asymmetry in terms of Kaluza-Klein extra dimensions

TL;DR

This paper proposes a mechanism where extra-dimensional evolution and internal angular momentum in Kaluza-Klein models generate the universe's matter-antimatter asymmetry, linking geometry to baryon/lepton number.

Contribution

It introduces a novel approach connecting extradimensional dynamics with baryon/lepton asymmetry through internal angular momentum in a multidimensional framework.

Findings

Internal angular momentum can accumulate in fermions.

The mechanism explains the origin of matter-antimatter asymmetry.

Symmetry emergence during inflation is demonstrated.

Abstract

In this article, we discuss the mechanism for generating the lepton/baryon number and its subsequent conservation based on extradimensional evolution. The internal angular momentum of extra space is related to the lepton/baryon charge. Extra space metric are 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.
