摘要：

粒子物理学的标准模型（SM）在最高能量的对撞机（LEP，赫拉，Tevatron，SLAC）上通过实验进行了非常精确的测试。唯一缺少的粒子是希格斯玻色子玻色子，这将是欧洲核子研究中心新的大型强子对撞机（LHC）搜索的第一个粒子。SM预测有三种类型的左手中微子。在日本、意大利、加拿大、俄罗斯和美国进行的关于大气和太阳中微子的实验表明，存在中微子振荡，这意味着中微子的质量差非常小，违反了单个轻子数的守恒。中微子振荡在长基线中微子实验中得到了验证（在日本和美国）;宇宙学对中微子质量的总和给出了相当精确的指示。在这个一般讲座将总结的SM的一些主要属性和一些主要结果在现场和准备中的实验。将简要讨论一些主要的未决问题。

英文摘要：

The Standard Model (SM) of Particle Physics was tested to great precision by experiments at the highest energy colliders (LEP, Hera, Tevatron, SLAC). The only missing particle is the Higgs boson, which will be the first particle to be searched for at the new Large Hadron Collider (LHC) at CERN. The SM anticipated that there are 3 types of left handed neutrinos. Experiments on atmospheric and solar neutrinos (made in Japan, Italy, Canada, Russia and the US) have shown the existence of neutrino oscillations, which imply that neutrinos have very small mass differences and violate the conservation of individual leptonic numbers. Neutrino oscillations were verified in long baseline neutrino experiments (in Japan and in the USA); and cosmology has given reasonably precise indications on the sum of the neutrino masses. In this general lecture will be summarized some of the main properties of the SM and some of the main results obtained in the field and the experiments in preparation. Some of the main open questions will be briefly discussed.
