The discovery of Higgs particle has ushered in a new era of particle physics. Even though the list of members of the standard theory of particle physics is now complete, the shortcomings of the theory became ever more acute. It is generally considered that the best solution to the problems is an electron–positron collider that can study Higgs particle with high precision and high sensitivity; namely, a Higgs factory. Among a few candidates for Higgs factory, the International Linear Collider (ILC) is currently the most advanced in its program. In this article, we review the physics and the project status of the ILC including its energy expandability.

国际直线对撞机项目-其物理和地位

希格斯粒子的发现开启了粒子物理学的新纪元。即使现在已经完成了粒子物理学标准理论的成员清单，该理论的缺点也变得更加尖锐。通常认为，解决该问题的最佳方法是一个电子-正负对撞机，它可以高精度和高灵敏度地研究希格斯粒子。即希格斯工厂。在希格斯工厂的一些候选人中，国际线性对撞机（ILC）目前是其计划中最先进的。在本文中，我们将回顾ILC的物理和项目状态，包括其能量可扩展性。
