Query: Flavor Problem, Proton Decay And Neutrino Oscillations In SUSY Models
  With Anomalous ${\cal U}(1)$   We discuss how realistic supersymmetric models can be constructed by
employing an anomalous ${\cal U}(1)$ flavor symmetry which also mediates
supersymmetry breaking. A judicious choice of ${\cal U}(1)$ charges enables the
first two squark families to be sufficiently heavy ($\stackrel{>}{_\sim}10$
TeV), so that flavor changing neutral currents as well as dimension five
nucleon decay are adequately suppressed. Using the SU(5) example, the charged
fermion mass hierarchies, magnitudes of the CKM matrix elements, as well as the
observed neutrino oscillations are simultaneously accommodated. We estimate the
proton lifetime to be $\tau_p\sim 10^3\cdot \tau_p[{\rm minimal} SU(5)]$, with
the decay mode $p\to K\mu $ being comparable to $p\to K\nu_{\mu, \tau}$.
