Abstract

We construct a supersymmetric SO(10) model with the asymptotic relation tanβ≃ m_t/m_b automatically arising from its structure. The model retains the significant Minimal Supersymmetric Standard Model predictions for sin² θ_w and α_s and contains an automatic Z₂ matter parity. Proton decay through d=5 operators is sufficiently suppressed. It is remarkable that no global symmetries need to be imposed on the model.
