Query: Lorentz Violation in Supersymmetric Field Theories   Broken spacetime symmetries might emerge from a fundamental physical theory.
The effective low-energy theory might be expected to exhibit violations of
supersymmetry and Lorentz invariance. Some illustrative models which combine
supersymmetry and Lorentz violation are described, and a superspace formulation
is given.
