论文摘要
我们为四维空间中的三个无质量的高旋转超塑料构建了一系列超对称立方顶点。我们使用类似框架的多方形式主义，可以避免大多数技术困难，并为玻色子和费米子提供统一的描述。我们的工作是基于所谓的弗拉德金 - 瓦西尔式形式主义，用于建造立方顶点，这需要非零的宇宙学常数。因此，我们首先在ADS空间中构造顶点，然后考虑固定限制。我们表明，广告超对称顶点是超级成分的四个基本顶点的总和，而与Metsaev的分类一致的平面限制中的一个顶点消失。
We construct a range of supersymmetric cubic vertices for three massless higher spin supermultiplets in the four-dimensional space. We use frame-like multispinor formalism, which allows to avoid most of the technical difficulties and provides a uniform description for bosons and fermions. Our work is based on the so-called Fradkin-Vasiliev formalism for construction of the cubic vertices, which requires the non-zero cosmological constant. Thus we first construct the vertices in AdS space and then consider the flat limit. We show that the AdS supersymmetric vertex is a sum of four elementary vertices for supermultiplet components, while one of the vertices vanishes in the flat limit in agreement with the Metsaev's classification.
