摘　　要：首先对粒子物理的基本目标、实验方法、研究现状以及粒子标准模型进行了简要介绍。解释了为何寻求超出标准模型的物理信号是现阶段物理学研究的核心任务。接着着重介绍了首个在粒子物理实验中被证实的超出标准模型的实验信号、中微子振荡及其实验测量,以及通向新物理原理的探针——希格斯(Higgs)玻色子。最后,介绍了高能物理实验设施,特别是现有的北京正负电子对撞机项目和未来的环形正负电子对撞机项目。对于后者,除了明晰其突出的物理学意义和物理学性能,还阐述了其对科学技术的促进作用。We made a brief introduction to the particle physics, including its scientific objective, experimental methodology, current status and explicitly the Standard Model. We explained why the searching for Beyond Standard Model signal is of key importance for nowadays＇ physics research. The first experimental evidence of the Beyond Standard Model signal, the neutrino oscillation, is discussed in details. Meanwhile, we discussed intensively the Higgs boson, which serves as an extremely sensitive probe to the new physics signal. The particle physics experimental facilities are briefly summarized in this manuscript, especially the Beijing Electron Positron Collider and the proposed Circular Electron Positron Collider. For the latter, we demonstrated its physics reach, physics potential, and described its synergy with industrial technology innovation.
