Prospects for Lorentz Invariance Violation searches with top pair production at the LHC and future hadron colliders

TL;DR

This paper explores the potential to detect Lorentz invariance violation through top quark pair production at current and future hadron colliders, aiming to significantly improve existing bounds in the top sector.

Contribution

It proposes a dedicated analysis method to enhance sensitivity to Lorentz violation in top quark production, potentially improving bounds by up to three orders of magnitude.

Findings

Bounds on Lorentz violation in the top sector can be greatly improved.

Future colliders will further enhance sensitivity to Lorentz invariance violation.

Current LHC data already provide significant constraints.

Abstract

This paper investigates a signature of Lorentz invariance violation with the $t\bar{t}$ production at the LHC and future hadron colliders. Possible deviations from the Lorentz symmetry remain poorly constrained in the top quark sector. With a dedicated analysis of $t\bar{t}$ events produced at the LHC, bounds in the top sector can be improved by up to three orders of magnitude relative to Tevatron, the only measurement existing so far. The sensitivity will be even further enhanced at the HL-LHC and future colliders.
