摘要：
We show that by introducing additional degrees of freedom with masses of the order of the electroweak scale the usual predictions for the proton lifetime and sin2-theta(W) obtained in the contexts of grand-unified-theory models with deserts can now be made to agree with current experimental data. We tabulate a number of possible quantum number assignments for these new particles.
