OPERA中微子并没有超光速
中微子 超光速 OPERA 相对论
2015/6/4
根据“吸纳了测不准原理的新狭义相对论”，针对OPERA中微子速度测量提出一个公式，计算结果显示该实验中μ中微子最高速度为(1-1.6×10-40)c，虽然极近光速但并没有达到光速。既然中微子的速度低于光速，为什么还会出现提前到达现象呢？其原因在于中微子以及所有轻子、夸克并不是点粒子。把提前到达时间δt的测量值代入这个公式可以估算出μ中微子的质量≈5×10-9eV/c2。该公式还指出，δt不随中微子...

Measurement of the atmospheric muon charge ratio with the OPERA detector
atmospheric muon OPERA detector
2010/3/16
The OPERA detector at the Gran Sasso underground laboratory (LNGS) was used to measure the atmospheric muon charge ratio in the TeV energy region. We analyzed 403069 atmospheric muons corresponding to...
