Abstract

The study of extra charged gauge boson beyond the Standard Model has always been of great interest. Future muon colliders will have a significant advantage in discovering exotic particles. In this paper, by studying the $\mu^+ \mu^- \to W^{\prime +} W^{\prime -} \to e^+ e^- n_e \bar{n}_e$ process, we explore the properties of $W^\prime$ in the alternative left-right model. The cross section and angular distribution of the final electron are investigated in the scenario of different $W^\prime$ mass and right-handed coupling constant. The forward-backward asymmetry is also an important observable to reflect the properties of $W^\prime$. We provide a method to effectively suppress the background processes. With specific kinematic cuts, the significance can reach $5.17\sigma$ for 4.8 TeV $W^\prime$ at the collision energy of 10 TeV.
