摘要

简介/目的:超对称是拉格朗日的一种超越李群的对称。它允许玻色子和费米子的交换。最重要的模型是最小超对称标准模型,简称MSSM。方法:超荷代数、超场、Grassmann数、Berezin积分。结果:超对称变换是全局的,不依赖于时空坐标。在超重力的情况下,它们是局部的。结论:超对称模型,尤其是MSSM,可以描述标准模型之外的更多物理和更多粒子。

Supersymmetry
Introduction/purpose: Supersymmetry is a symmetry of the Lagrangian that goes beyond Lie groups. It allows the exchange of bosons and fermions. The most important model is the Minimal Supersymmetric Standard Model, or MSSM. Methods: Supercharge algebra, superfields, Grassmann numbers, Berezin integral. Results: Supersymmetric transformations are global, they do not depend on spacetime coordinates. In the case of Supergravity, they are local. Conclusion: Supersymmetric models, and MSSM in particular, could describe more physics and more particles beyond the Standard Model.
