对称、高阶对称和超对称

Symmetries, higher order symmetries and supersymmetries

Andrea Ferrantelli

摘要:

我们讨论的几何公式的规范场理论,称为规范自然,这主要是在都灵大学(意大利)和马萨里克大学在布尔诺(捷克共和国)。在这个框架中,某个合适的主丛P的自同构群,称为结构丛,通过规范变换作用于场。在表明经典的Wess-Zumino模型可以在这种形式主义中一致地描述之后,我们考虑最小超引力(mSugra)。我们发现,要将mSugra嵌入到Gauge-Natural框架中,还需要进一步的研究。这是因为拉里塔-施温格拉格朗日量的协方差和超对称代数的闭包都发生在壳上。

英文摘要:

We discuss a geometrical formulation for gauge field theories, called Gauge-Natural, which has been mostly developed at the University of Turin (Italy) and at the Masaryk University in Brno (Czech Republic). In this framework, the group of automorphisms of some suitable principal bundle P, called the structure bundle, acts on fields by means of gauge transformations. After showing that the classical Wess-Zumino model can be consistently described within this formalism, we consider minimal supergravity (mSugra). We find that to embed mSugra in a Gauge-Natural framework, further investigations are needed. This happens since both the covariance of the Rarita-Schwinger Lagrangian and the closure of the SUSY algebra occur on-shell.
