The Noncommutative Standard Model and Polarization in Charged Gauge Boson Production at the LHC

TL;DR

This paper investigates how noncommutative geometry affects charged gauge boson production at the LHC, proposing new observables to distinguish different types of noncommutativity using polarization and angular distributions.

Contribution

It introduces a method to analyze polarization and angular distributions to identify noncommutative effects in charged gauge boson production at the LHC.

Findings

Polarization-sensitive observables can separate space-time from space-space noncommutativity.

Angular distributions help reconstruct polarized cross sections.

New CP-sensitive observables enhance detection of noncommutative signatures.

Abstract

We study the pair production of charged gauge bosons at the LHC in a noncommutative extension of the standard model. We use angular distributions in the decays of the gauge bosons to partially reconstruct polarized cross sections. We use this, together with CP considerations, to construct more sensitive observables that allow to separate space-time from space-space noncommutativities.
