Supersymmetric SO(10) And A Prediction For θ₁₃

We present a predictive scheme for fermion masses and mixings based on supersymmetric SO(10) which provides an understanding of the observed hierarchies in the charged fermion sector including CKM mixings. In the neutrino sector bi-large mixing can be realized, while the third leptonic mixing angle $\theta_{13}\simeq 0.01 - 0.2$.
