Abstract

In this paper, we review the fundamental aspects of N=1 supergravity and employ the chiral formalism to describe spin-32 fermions. Armed with this, we analyze the discrete symmetries of the graviton in the context of linearized gravity (LG) and Rarita-Schwinger (RS) fields, which include the description of the gravitino. Additionally, we highlight the advantages of the chiral formalism in classifying Lorentz and CPT-violating terms in RS theories, extending these models by including Lorentz-violating operators, as has been done in LG.

手性费米子形式论中的CPT对称性及其破缺

在本文中，我们回顾了 N=1 超引力的基本方面，并运用手性形式主义来描述自旋-32 费米子。有鉴于此，我们在线性化引力（LG）和拉里塔-施文格（RS）场的背景下分析了引力子的离散对称性，其中包括对引力子的描述。此外，我们还强调了手性形式主义在对 RS 理论中的洛伦兹和 CPT 违反项进行分类方面的优势，并通过在 LG 中加入洛伦兹违反算子来扩展这些模型。美国物理学会出版 2025
