TL;DR

This paper investigates the potential to detect a new charged gauge boson $W'$ through the subprocess $eq\to\nu q'$ at future $e^{+}e^{-}$ and $ep$ colliders, highlighting its sensitivity to new physics models.

Contribution

It analyzes the $W'$ contributions to the process $eq\to\nu q'$ within little Higgs and Higgsless models, proposing this as a method to distinguish new physics at future colliders.

Findings

The process $eq\to\nu q'$ is sensitive to the $W'$ coupling.

This process can differentiate between various new physics models.

Potential for $W'$ detection at future colliders.

Abstract

In the framework of the little Higgs models and the three-site Higgsless model, we discuss the contributions of the new charged gauge boson $W'$ to the process $eq\to\nu q'$ and the possibility of detecting $W'$ via this process in future high energy linear $e^{+}e^{-}$ collider $(ILC)$ and $ep$ collider $(THERA)$ experiments. Our numerical results show that the process $eq\to\nu q'$ is rather sensitive to the coupling $W'ff'$ and one can use this process to distinguish different new physics models in future $ILC$ and $THERA$ experiments.
