NEUTRINO OSCILLATION EXPERIMENTS——TESTS BEYOND THE STANDARD MODEL(Ⅰ)
-
摘要: 文章总结了中微子振荡实验的历史和现状.介绍了几个太阳中微子丢失实验的结果和几个大气μ中微子丢失实验结果.这些结果表明存在中微子振荡,即中微子具有质量.它是超出标准模型的信号.文章还介绍了21世纪初研究中微子振荡的若干重要实验,例如长基线中微子振荡实验以及建造μ子贮存环来产生高能电子中微子束进行中微子振荡的实验以及测量中微子振荡时的CP破坏的设想.Abstract: The history and status of neutrino oscillation experiments are summarized. Several experimental results on missing solar neutrinos and atmospheric muon neutrinos are described. These results imply that there are neutrino oscillations, which means that neutrinos have mass. This is signal of beyond the standard model. Several important experiments on neutrino oscillation at the beginning of the 21st century, such as long-base-line neutrino oscillation, the idea to build a muon storage ring for producing a high energy electron neutrino beam to perform neutrino oscillation experiments and to measure the CP violation in neutrino oscillation, are also reviewed.
