标题： Cubic interaction vertices for massless higher spin supermultiplets in d=4

摘要： 我们构造了四维空间中三组无质量高自旋超多重态的超对称三次顶点的一系列可能性。 我们使用框架形式的多自旋公式，这可以避免大部分技术上的困难，并且为玻色子和费米子提供统一的描述。 我们的工作基于所谓的Fradkin-Vasiliev公式来构建三次顶点，该公式要求非零宇宙常数。 因此，我们首先在反德西特（AdS）空间中构建顶点，然后考虑平坦极限。 我们证明了AdS超对称顶点是超多重态分量的四个基本顶点之和，其中有一个顶点在平坦极限下消失，与Metsaev的分类一致。 显示英文摘要

摘要： 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.
