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 μ⁺ μ^- → W^{′ +} W^{′ -} → e⁺ e^- n_e n_e process, we explore the properties of W^′ in the alternative left-right model. The cross section and angular distribution of the final electron are investigated in the scenario of different W^′ mass and right-handed coupling constant. The forward-backward asymmetry is also an important observable to reflect the properties of W^′. We provide a method to effectively suppress the background processes. With specific kinematic cuts, the significance can reach 5.17σ for 4.8 TeV W^′ at the collision energy of 10 TeV.
