AI 中文总结

本研究针对非壳$\boldsymbol{\textit{N}=2}$外尔与爱因斯坦超引力,推导了其解析预势的Wess-Zumino规范相关的场重定义、变换律等,以耦合超引力的自由超多重态作用量为应用,仅分析玻色子部分。

AI 中文摘要

我们对非壳$\boldsymbol{\textit{N}=2}$外尔超引力和$\boldsymbol{\textit{N}=2}$爱因斯坦超引力(带非线性张量补偿子的版本)的解析预势的Wess-Zumino规范展开了全面研究,推导了场重定义、完整变换律以及保持Wess-Zumino规范的规范超参数。作为所得结果的具体应用,我们考察了耦合于$\boldsymbol{\textit{N}=2}$超引力的自由超多重态作用量的分量结构,本研究将分析严格限制在玻色子部分。

英文摘要

We present a comprehensive study of the Wess-Zumino gauge for the analytic prepotentials of the off-shell $\mathcal{N}=2$ Weyl and $\mathcal{N}=2$ Einstein supergravities (the version with a non-linear tensor compensator). The field redefinitions, the full transformation laws, and the gauge superparameters that preserve the Wess-Zumino gauge are derived. As a concrete application of the obtained results, we examine the component structure of the free hypermultiplet action coupled to $\mathcal{N}=2$ supergravity. In this work, we restrict our analysis strictly to the bosonic sector.
