部分无质量自旋5/2与超对称

Partially massless spin 5/2 and supersymmetry

Yu. M. Zinoviev

AI总结:

本文研究部分无质量自旋5/2超多重态,通过类框架规范不变形式和Fradkin-Vasiliev形式构造其与无质量引力微子的局域超对称相互作用,并利用场重定义自由度和展开方程解决Stueckelberg场带来的歧义。

摘要:

我们详细阐述了部分无质量自旋5/2超多重态,它包含部分无质量自旋5/2、无质量和部分无质量自旋2,以及无质量自旋3/2。我们考虑了将部分无质量自旋5/2与其两个可能的超伙伴——无质量和部分无质量自旋2——联系起来的整体超变换,并通过引入与无质量引力微子的相互作用使其局域化。我们使用类框架规范不变形式来描述自由场,并使用Fradkin-Vasiliev形式来构造相互作用。由于在有质量和部分无质量场的规范不变描述中存在Stueckelberg场,我们面临与场重定义相关的歧义。我们利用这一自由度来简化计算。同时,我们展示了如何利用展开方程来解决这些歧义。

英文摘要:

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.
