The objective of particle physics is to discover what the universe is made of and how it works. Our quest to understand nature has produced a remarkably successful understanding of the structure of matter, described by the Standard Model of particle physics. However, we know that the Standard Model is incomplete for (at least) two reasons: it fails to explain the extreme weakness of gravity compared to the other forces of nature, and it is unable to account for the "dark matter" that makes up about 80% of the mass in the universe. Also, the Standard Model's explanation for the origin of mass of ordinary particles, the so-called Higgs mechanism, is still experimentally untested. We have come now to a very exciting time when experiments in the next few years (particularly at the Large Hadron Collider, now in its second year of operation at CERN in Geneva, Switzerland) are expected to provide answers to these questions.

粒子物理学的目标是发现宇宙是由什么组成的，以及它是如何工作的。我们对理解自然的追求已经产生了对物质结构的非常成功的理解，这是由粒子物理学的标准模型描述的。然而，我们知道标准模型是不完整的，原因（至少）有两个：它无法解释引力相对于其他自然力的极端脆弱性，并且它无法解释占宇宙质量约80%的“暗物质”。此外，标准模型对普通粒子质量起源的解释，即所谓的希格斯机制，仍然未经实验检验。我们现在已经到了一个非常激动人心的时刻，在未来几年的实验中（特别是在大型强子对撞机上，现在在瑞士日内瓦的欧洲核子研究中心运行的第二年），预计将为这些问题提供答案。
