Query: Proton decay in SO(10) SUSY GUTs   We calculate the proton lifetime in an SO(10) supersymmetric grand unified
theory [SUSY GUT] with U(2) family symmetry. This model fits the low energy
data, including the recent data for neutrino oscillations. We discuss the
predictions of this model for the proton lifetime in light of recent
SuperKamiokande results which significantly constrain the SUSY parameter space
of the model.
