Probing Space-Time Noncommutativity in the Bhabha Scattering
Linda Ghegal

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 . This study is based on the definition of the noncommutativity parameter that we have assumed. We explore the noncommutative scale TeV considering different machine energy ranging from TeV to TeV.
