Atomic Parity Violation (APV) is usually quantified in terms of the weak nuclear charge QW of a nucleus, which depends on the coupling strength between the atomic electrons and quarks. In this work, we review the importance of APV to probing new physics using effective field theory. Furthermore, we correlate our findings with the results from neutrino-nucleus coherent scattering. We revisit signs of parity violation in polarized electron scattering and show how precise measurements on the Weinberg's angle give rise to competitive bounds on light mediators over a wide range of masses and interactions strengths. Our bounds are firstly derived in the context of simplified setups and then applied to several concrete models, namely Dark Z, Two Higgs Doublet Model-U(1)X and 3-3-1, considering both light and heavy mediator regimes.

新的物理探针:违反原子奇偶性,极化电子散射和中微子-核相干散射

通常用弱核电荷来量化违反原子奇偶校验(APV) w ^原子核的原子数取决于原子电子与夸克之间的耦合强度。在这项工作中,我们回顾了APV在使用有效场论探测新物理学中的重要性。此外,我们将我们的发现与中微子核相干散射的结果相关联。我们重新审视了极化电子散射中奇偶校验违规的迹象,并显示了在广泛的质量和相互作用强度下,温伯格角的精确测量如何在光介体上产生竞争界限。我们的边界首先是在简化设置的背景下得出的,然后应用于多个具体模型,即Dark Z,Two Higgs Doublet Model-ü1个X 和3-3-1,同时考虑了轻度和重度调解人制度。
