Probing Space-Time Noncommutativity in the Bhabha Scattering

TL;DR

This paper explores how space-time noncommutativity affects Bhabha scattering within a noncommutative standard model, estimating the noncommutative scale using collider energies from 0.5 to 1.5 TeV.

Contribution

It provides a first-order analysis of noncommutative effects on Bhabha scattering using the Seiberg-Witten approach and estimates the noncommutative scale based on collider energies.

Findings

Noncommutative scale $\\Lambda_{_{NC}}$ is at least 0.8 TeV.

Noncommutative effects become relevant at high energies.

The study constrains noncommutativity parameters using collider data.

Abstract

We investigate Bhabha scattering with the Seiberg-Witten expended noncommutative standard model scenario to first order of the noncommutativity parameter $\Theta_{\mu \nu }$. This study is based on the definition of the noncommutativity parameter that we have assumed. We explore the noncommutative scale $\Lambda_{_{NC}}\geq0.8$ TeV considering different machine energy ranging from $0.5$ TeV to $1.5$ TeV.
