The exotic neutral gauge boson is a powerful candidate for the new physics beyond the standard model. As a promising model, the left-right symmetric model has been proposed to explain the neutrino mass, dark matter, and matter-antimatter asymmetry, etc., in which exotic gauge bosons Z^′, W′ ± have been put forward as well as other new right-handed particles. We investigate the μ+ μ- → qq and μ+ μ- → l+ l- processes involving the Z^′ boson as an intermediate particle. The coupling strength, decay width and mass are the key parameters on the production and decay processes of the Z^′ boson. The results indicate that the angular distributions of final particles are sensitive to the couplings of Z^′ to the other fermions. Asymmetries defined from the angular distributions are ideal quantities to demonstrate the discrepancy between the standard model process and the processes with Z^′ participated and they are also appropriate observables to discriminate the couplings of Z^′ to other particles. Compared with the current results at the Large Hadron Collider (LHC), the future muon collider has a great potential to explore the new parameter space with Z^′ boson.
