自然性与超对称性的地位

Naturalness and the Status of Supersymmetry

Jonathan L. Feng

摘要:

几十年来,弱尺度的不自然性一直是激发新粒子物理学的主要问题,而弱尺度超对称性一直是主要的解决方案。这一范式现在正受到大量实验数据的挑战。在这篇综述中,我们首先回顾了弱尺度超对称性的理论动机,包括规范层次问题,大统一和WIMP暗物质,以及它们对超伙伴质量的影响。这些都是针对对撞机搜索的超对称性的主要约束,希格斯玻色子质量,以及风味和CP破坏的低能约束。然后,我们批判性地审视了量化超对称性自然性的尝试,强调了许多主观选择对结果的定量和定性影响。最后,我们综述了自然超对称模型的各种建议,包括有效超对称性,焦点超对称性,压缩超对称性和R-宇称破坏超对称性,并总结了它们的关键特征,现状和对未来实验的影响。

英文摘要:

For decades, the unnaturalness of the weak scale has been the dominant problem motivating new particle physics, and weak-scale supersymmetry has been the dominant proposed solution. This paradigm is now being challenged by a wealth of experimental data. In this review, we begin by recalling the theoretical motivations for weak-scale supersymmetry, including the gauge hierarchy problem, grand unification, and WIMP dark matter, and their implications for superpartner masses. These are set against the leading constraints on supersymmetry from collider searches, the Higgs boson mass, and low-energy constraints on flavor and CP violation. We then critically examine attempts to quantify naturalness in supersymmetry, stressing the many subjective choices that impact the results both quantitatively and qualitatively. Finally, we survey various proposals for natural supersymmetric models, including effective supersymmetry, focus point supersymmetry, compressed supersymmetry, and R-parity-violating supersymmetry, and summarize their key features, current status, and implications for future experiments.
