Abstract

We report on a recent progress in constructing off-shell \(4\) D, \(\mathcal{N}=2\) supersymmetric integer higher-superspin theory in terms of unconstrained harmonic analytic gauge superfields and their cubic interaction with matter hypermultiplets. For even superspins, a new equivalent representation of the hypermultiplet couplings in terms of an analytic \(\omega\) superfield is presented. It involves both cubic and quartic vertices.

调和超空间中的更高自旋

摘要

我们报告了根据无约束调和解析规范超场及其与物质超多重态的立方相互作用构建离壳\(4\) D, \(\mathcal{N}=2\)超对称整数高超自旋理论的最新进展。即使对于超自旋，也提出了用解析\(\omega\)超场表示超多重态耦合的新等效表示。它涉及三次和四次顶点。
