A Chern-Simons model for baryon asymmetry

TL;DR

This paper proposes a high-energy Chern-Simons based model with supersymmetric preons that explains baryon asymmetry and transitions to the Standard Model at lower energies, providing a potential link from early universe physics to known particle physics.

Contribution

It introduces a novel Chern-Simons and supersymmetric preon model that describes physics from the Big Bang scale down to the Standard Model, including baryon asymmetry generation.

Findings

Baryon-to-photon ratio n_B/n_gamma << 1.

Model transitions from preon-based at high energies to pointlike quarks and leptons.

Provides a topological mass mechanism for gauge symmetry breaking.

Abstract

In search of a phenomenological model that would describe physics from Big Bang to the Standard Model (SM), we propose a model with the following properties (i) above an energy about Lambda_{cr} > 10^{16} GeV there are Wess-Zumino supersymmetric preons and Chern-Simons (CS) fields, (ii) at Lambda_{cr} ~ 10^{16} GeV spontaneous gauge symmetry breaking takes place in the CS model and the generated topological mass providing attractive interaction to equal charge preons, and (iii) well below 10^{16} GeV the model reduces to the standard model with essentially pointlike quarks and leptons, having a radius ~ 10^{-31} m. The baryon asymmetry turns out to have a fortuitous ratio n_B/n_gamma << 1.
