Location and Direction Dependent Effects in Collider Physics from Noncommutativity

TL;DR

This paper investigates how noncommutative geometry affects collider physics measurements, revealing that Earth's rotation and orientation influence observable effects, and uses LEP data to constrain noncommutative parameters.

Contribution

It introduces a model accounting for Earth's rotation and orientation in noncommutative corrections to collider cross sections, providing new bounds on noncommutative parameters.

Findings

LEP data constrains noncommutative scale and orientation.

Earth's rotation affects noncommutative correction measurements.

Potential implications for future collider experiments.

Abstract

We examine the leading order noncommutative corrections to the differential and total cross sections for e+ e- --> q q-bar. After averaging over the earth's rotation, the results depend on the latitude for the collider, as well as the direction of the incoming beam. They also depend on scale and direction of the noncommutativity. Using data from LEP, we exclude regions in the parameter space spanned by the noncommutative scale and angle relative to the earth's axis. We also investigate possible implications for phenomenology at the future International Linear Collider.
