Spontaneous CPT asymmetry of the Universe

TL;DR

This paper explores the implications of spontaneous CPT symmetry breaking in extended QED, analyzing its potential effects on cosmic anisotropy, particle mass differences, and high-energy electron decay processes.

Contribution

It introduces a model of extended QED with CPT violation and examines its phenomenological consequences relevant to large-scale universe anisotropy.

Findings

Potential mass splitting between electrons of different helicities.

Decay of high-energy electrons into lower energy particles.

Implications for large-scale anisotropy of the Universe.

Abstract

The extended QED with renormalizable interactions breaking the Lorentz and CPT symmetry is considered and the phenomenological consequences of such a symmetry breaking are illuminated in view of recent discussion of large scale anisotropy of the Universe. Other physical effects in QED with CPT violation are examined, in particular, mass splitting between electrons of different helicities and decay of very high energetic electrons into lower energy electrons and positrons.
