Findings

Models retain supersymmetry with Lorentz violation.

Lorentz-violating terms derived from superspace transformations.

Framework for exploring symmetry-breaking in supersymmetric theories.

Abstract

Superfield realizations of Lorentz-violating extensions of the Wess-Zumino model are presented. These models retain supersymmetry but include terms that explicitly break the Lorentz symmetry. The models can be understood as arising from superspace transformations that are modifications of the familiar one in the Lorentz-symmetric case.
