俄罗斯国家研究中心库尔恰托夫研究所Zinoviev, Yu. M.团队提出了部分无质量自旋5/2和超对称。相关论文于2025年6月5日发表在《高能物理杂志》上。

研究组详细阐述了部分无质量自旋5/2超多重态，其中包含部分无质量自转5/2、无质量和部分无质量旋转2，以及无质量自旋3/2。他们考虑将部分无质量自旋5/2与其两个可能的超伙伴（无质量自旋和部分无质量旋转2）连接起来的全局超变换，并通过切换与无质量引力子的相互作用使它们成为局部的。

研究组使用类似框架的规范不变形式来描述自由场，使用Fradkin-Vasiliev形式来构建相互作用。由于在大规模和部分无质量场的规范不变描述中存在Stueckelberg场，他们面临着与场重新定义相关的模糊性。研究组利用这种自由来简化计算。同时还演示了如何使用展开的方程来解决这些歧义。

Abstract: We elaborate on the partially massless spin 5/2 supermultiplet, which contains partially massless spin 5/2, massless and partially massless spin 2, as well as massless spin 3/2. We consider the global supertransformations connecting partially massless spin 5/2 to its two possible superpartners, massless and partially massless spin 2, and make them local by switching the interaction with the massless gravitino. We use a frame-like gauge-invariant formalism to describe free fields and the Fradkin-Vasiliev formalism to construct interactions, Due to the presence of the Stueckelberg fields in the gauge-invariant description of massive and partially massless fields, we face ambiguities related to field redefinitions. We use this freedom to simplify calculations. At the same time, we demonstrate how these ambiguities can be resolved using unfolded equations.
