This paper shows that the positive-energy and non-renormalization theorems oftraditional supersymmetry survive the addition of Lorentz violatinginteractions. The Lorentz-violating coupling constants in theories using theconstruction of Berger and Kostelecky must obey certain constraints in order topreserve the positive energy theorem. Seiberg's holomorphic arguments are usedto prove that the superpotential remains non-renormalized (perturbatively) inthe presence of Lorentz-violating interactions of the Berger-Kostelecky type.We briefly comment on Lorentz-violating theories of the type constructed byNibbelink and Pospelov to note that holomorphy arguments offer elegant proofsof many non-renormalization results, some known by other arguments, some new.
