Noncommutative Standard Model in Top Quark Sector

TL;DR

This paper investigates the constraints on noncommutative geometry parameters in the Standard Model by analyzing top quark and W boson data from the CDF experiment, providing bounds on the noncommutative scale.

Contribution

It offers the first estimation of bounds on the noncommutative scale using top quark and W boson polarization measurements from Tevatron data.

Findings

Established 95% exclusion contours for noncommutative parameters.

Derived bounds on the noncommutative scale $\\Lambda_{NC}$.

Provided constraints based on recent experimental measurements.

Abstract

In this article we aim to estimate the bounds on the noncommutative scale $\Lambda_{NC}$ and to extract the 95% exclusion contours for some $\theta_{\mu\nu}$ components using the recent measurements of the top quark width and the $W$ boson polarization in top pair events from CDF experiment at Tevatron.
