Chiral Anomaly Beyond Lorentz Invariance

TL;DR

This paper investigates the persistence of the chiral anomaly in an extended standard model that incorporates minimal Lorentz invariance violation, suggesting its fundamental nature beyond relativistic symmetry.

Contribution

It demonstrates that the chiral anomaly remains valid even when Lorentz invariance is minimally violated, extending its applicability beyond traditional relativistic frameworks.

Findings

Chiral anomaly persists despite Lorentz invariance violation

Bounds from light speed measurements constrain Lorentz violation effects

Results suggest anomaly's fundamental role beyond relativistic symmetry

Abstract

The chiral anomaly in the context of an extended standard model with minimal Lorentz invariance violation is studied. Taking into account bounds from measurements of the speed of light, we argue that the chiral anomaly and its consequences are general results valid even beyond the relativistic symmetry.
