Query: Constraining Z' From Supersymmetry Breaking   We suggest and analyze a class of supersymmetric Z' models based on the gauge
symmetry U(1)_x = x Y - (B-L), where Y is the Standard Model hypercharge. For 1
< x < 2, the U(1)_x D-term generates positive contributions to the slepton
masses, which is shown to solve the tachyonic slepton problem of anomaly
mediated supersymmetry breaking (AMSB). The resulting models are very
predictive, both in the SUSY breaking sector and in the Z' sector. We find M_Z'
= (2-4) TeV and the Z-Z' mixing angle \xi = 0.001. Consistency with symmetry
breaking and AMSB phenomenology renders the Z' "leptophobic", with Br(Z' -> e^+
e^-) = (1-1.6)% and Br(Z' -> q q-bar) = 44%. The lightest SUSY particle is
either the neutral Wino or the sneutrino in these models.
