希格斯玻色子——物质质量起源的探索

Higgs boson——an exploration of the origin of matter mass

2012年7月4日,欧洲核子中心大型强子对撞机上的ATLAS和CMS实验组联合宣布发现了一个标量粒子,其性质与标准模型理论预言的希格斯粒子初步吻合,随后被大量实验数据进一步证实。作为唯一的基本标量(自旋为零)粒子,希格斯粒子在标准模型中占据极其特殊的地位,因此,希格斯粒子相关性质的理论研究是理论粒子物理研究的热点。文章简要介绍了希格斯粒子物理的理论问题及其进展。

On July 4,2012,the ATLAS and CMS collaborations at the Large Hadron Collider at CERN jointly announced the discovery of a scalar particle with properties similar to the Higgs particle predicted by the Standard Model;this was confirmed afterward by a large number of experimental data.As the only fundamental scalar(spin-zero)particle,the Higgs boson occupies a unique position in the Standard Model,so the study of its properties is a hot topic in theoretical particle physics.This paper briefly discusses the theoretical problems and progress of Higgs particle physics.
