AI 中文摘要
在本研究中，我们将无质量N=1超引力与大质量(2,3/2,3/2,1)超多重态的相互作用视为大引力的超对称扩展候选方案。研究采用了规范不变的大质量自旋2、自旋3/2及自旋1场描述，过程中出现了与可能的场重定义相关的歧义，这些歧义通过近期提出的基于 unfolded方程的方法得以解决，且我们仅考虑导数数量最少的相互作用（玻色子顶点为2阶导数，费米子顶点为1阶导数），这一处理似乎完全确定了整个构建过程。
英文摘要
In this work, we consider the interaction of massless $N=1$ supergravity with a massive (2,3/2,3/2,1) supermultiplet, as a possible candidate for a supersymmetric extension to bigravity. A gauge invariant description for massive spin-2, spin-3/2 and spin-1 fields is used. As a result of this, ambiguities arise related to possible field redefinitions, which are fixed by using a recently proposed method based on unfolded equations, and by restricting ourselves to interactions with the minimum number of derivatives (two for bosonic and one for fermionic vertices). It appears that this completely fixes the entire construction.
