The SO(10) model is a candidate for the unification of electromagnetic, weak, and strong interactions. The range of the Z' mass is 495 GeV < m(z') < 10(9) GeV. The formulas for the width and asymmetry for Z' decay depend only on the Z' mass. We apply the method of Boudjema et al. to identify a theoretical origin of the Z' boson in SO(10) and compare with other models.
