The new charged gauge boson $W^{\prime }$ and the subprocess $eq\to \hat{I}½q^{\prime }$ at $e^{+}{e}^{-}$ and $ep$ 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 $W^{\prime }$ to the process $eq\to \hat{I}½q^{\prime }$ and the possibility of detecting $W^{\prime }$ via this process in future high energy linear $e^{+}{e}^{-}$ collider $(ILC)$ and $ep$ collider $(THERA)$ experiments. Our numerical results show that the process $eq\to \hat{I}½q^{\prime }$ is rather sensitive to the coupling $W^{\prime }f{f}^{\prime }$ and one can use this process to distinguish different new physics models in future $ILC$ and $THERA$ experiments.
