The new charged gauge boson $W'$ and the subprocess $eq\toνq'$ 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 $W'$ to the process $eq\toνq'$ 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 $eq\toνq'$ 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.
