标题： Experimental Particle Physics Priorities 2025: A String Phenomenology Perspective

摘要： 随着美国SNOWMASS 2021进程和正在进行的欧洲战略报告2025，基础粒子物理学领域正在经历详细的社区评估，而需要大量公共投资的实验粒子物理学项目也正受到审查。我们从弦现象学的角度提供当前实验粒子物理学优先事项的评估。弦理论为量子引力提供了摄动一致的框架。弦现象学旨在连接弦理论与观测数据。弦理论是一种包含物质和其他基本相互作用的基本组成部分的一致的量子引力理论。由于所有形式的能量都与引力耦合，弦理论提供了一个框架，可以重现粒子物理学标准模型的结构，并产生超出标准模型的详细物理情景，{\it 例如}暗物质候选者，轴子，额外规范对称性等。鉴于这种广泛性，我们认为从弦现象学的角度来看，实验粒子物理学的优先事项是希格斯玻色子的本质和电弱对称破缺机制。未来理想的研究这一领域的设施是在10-15年内可以从决策开始建造的利用当代磁技术的50-60 TeV的强子对撞机。 显示英文摘要

摘要： With the SNOWMASS 2021 process in the US and the on--going European Strategy Report 2025, the field of elementary particle physics is undergoing detailed community evaluation, and the experimental particle physics program, which requires substantial public investment, is under scrutiny. We offer an assessment of the current experimental particle physics priorities from a string phenomenology point of view. String theory provides a perturbatively consistent framework for quantum gravity. String phenomenology aims to connect between string theory and observational data. String theory is a consistent theory of quantum gravity that contains the other fundamental constituents of matter and interactions. As all forms of energy couple to gravity, string theory provides a framework that reproduces the structures of the Standard Model of particle physics and gives rise to detailed physics scenarios beyond the Standard Model, {\it e.g.} dark matter candidates, axions, additional gauge symmetries, etc. Given this breadth, we propose that from a string phenomenology perspective, the experimental particle physics priority is the nature of the Higgs boson and the electroweak symmetry breaking mechanism. An ideal facility in the near future to study this sector is a hadron collider at 50--60 TeV that utilises contemporary magnet technology and can be built in 10--15 years from decision.
