Indeed , as our chart shows , the muon and the tau were discovered before anyone had predicted their existence .
实际上,正如经济学人图表所示,介子和τ介子在被人预测到存在前即被发现。
Yesterday - 6 / 28 - they even celebrated tau day in math events worldwide .
他们甚至在6月28日在世界各地数学活动中庆祝“τ日”。
Then there are neutrinos , w and z bosons , the electron-like muon and tau particles , and gluons-which hold quarks together in groups .
然后还有中微子,w和z波色子,类电子的μ粒子和τ粒子,还有胶子它的作用是将夸克聚合成团。
The team prepares a beam of just one type , muon neutrinos , sending them from cern to an underground laboratory at gran sasso in italy to see how many show up as a different type , tau neutrinos .
