摘要

讨论了在超场形式化的超场理论中实现洛伦兹对称破缺的三种方式，即超对称代数的变形，引入其分量可以依赖于违反洛伦兹(LV)向量(张量)的额外超场，以及在超场作用中加入与违反LV向量(张量)成比例的新项。我们用量子计算的例子来说明这些方法。

Lorentz-Symmetry Breaking and Supersymmetry

We discuss three manners to implement Lorentz symmetry breaking in a superfield theory formulated within the superfield formalism, that is, deformation of the supersymmetry algebra, introducing of an extra superfield whose components can depend on Lorentz-violating (LV) vectors (tensors), and adding of new terms proportional to LV vectors (tensors) to the superfield action. We illustrate these methodologies with examples of quantum calculations.
