Quark and the spontaneous broken symmetry

  • Online:2009-07-20 Published:2009-07-20

摘要: 用普通物理和原子物理的语言论述了对称性破缺机制和理论模型,介绍了2008年度诺贝尔物理学获奖者小林诚(Makoto Kobayashi)、益川敏英(Toshihide Maskawa)关于弱相互作用的理论模型(KM模型)和对称性破缺的起源,它是对电弱统一理论的完美补充;详细分析了在微观粒子世界系列实验中对称性自发破缺和夸克的发现.

关键词: 夸克, 对称性, 破缺, 机制

Abstract: The mechanism of spontaneous broken symmetry and its model are discussed in the language of fundamental physics, also, the discovery of the mechanism of spontaneous broken symmetry in subatomic physics by Yoichiro Nambu and the discovery of the origin of the broken symmetry by Makoto Kobayashi and Toshihide Maskawa are introduced. The experiments of the discovery of the least three families of quarks are presented.

Key words: quark, symmetry, broken, mechanism
