Abstract

At the present time (2022), there are discrepancies with the predictions of the Standard Model in several observables involving b → sℓ+ℓ− and [Formula: see text] decays. These are the B flavor anomalies. In this review, we summarize the data as of Moriond 2021 and present theoretical new physics explanations from both a model-independent effective field theory point of view and through the building of explicit models. Throughout, we stress the complementarity of these two approaches. In addition, we discuss combined explanations of both B anomalies and present models that also explain other problems, such as dark matter, ( g − 2)μ, neutrino properties, and hadronic anomalies.

B风味异常:2021年理论现状报告

目前（2022年），在涉及b的几个可观测值中，与标准模型的预测存在差异→ sℓ+ℓ− [公式：见正文]衰变。这些是B味异常。在这篇综述中，我们总结了截至Moriond 2021的数据，并从独立于模型的有效场论角度和通过建立显式模型提出了新的理论物理解释。自始至终，我们都强调这两种方法的互补性。此外，我们还讨论了B异常和现有模型的组合解释，这些模型也解释了其他问题，如暗物质、（g−2）μ、中微子性质和强子异常。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
