AI 中文摘要
标准模型（SM）规范群的手征阿贝尔扩展可能为解释各种超出标准模型（BSM）现象提供重要的新可能性，这类模型在文献中探索较少，目前仅报告了少量实验约束，使得大部分参数空间仍可用于新物理（NP）现象学研究。本文考虑三种无反常的手征阿贝尔扩展，检验其对应低能标参数空间与观测到的 $(g-2)_e$ 反常的兼容性，分析得出严格的排除限，结合现有实验边界后，完全排除了所考虑的手征模型。
英文摘要
Chiral Abelian extensions of the Standard Model (SM) gauge group may offer significant new possibilities for explaining various Beyond the Standard Model (BSM) phenomena within a common framework. The models being less explored in the literature only a few experimental constraints have been reported to date, leaving a major portion of the parameter space available for the New Physics (NP) phenomenology. The present paper considers three anomaly-free chiral Abelian extensions and examines the compatibility of the corresponding low-scale parameter spaces with the observed $(g-2)_e$ anomaly. The analysis results in stringent exclusion limits, completely ruling out the considered chiral models when used in complementarity with the existing experimental bounds.
