Lorentz violation and deep inelastic scattering

TL;DR

This paper investigates how potential Lorentz violation in quarks could affect deep inelastic scattering experiments, establishing initial constraints on Lorentz-violating coefficients using existing data.

Contribution

It provides the first constraints on quark-sector Lorentz violation coefficients derived from deep inelastic scattering data.

Findings

Existing data constrains Lorentz violation coefficients at parts per million level.

First quantitative bounds on quark-sector Lorentz violation from scattering experiments.

Demonstrates the utility of high-energy scattering data in testing fundamental symmetries.

Abstract

The effects of quark-sector Lorentz violation on deep inelastic electron-proton scattering are studied. We show that existing data can be used to establish first constraints on numerous coefficients for Lorentz violation in the quark sector at an estimated sensitivity of parts in a million.
