neutrinos that emerge at Gran Sasso start off as a beam of proton particles at Cern.───的中微子来自欧洲核子研究中心的质子粒子束。
They also measure the time distribution of neutrinos arriving at Gran Sasso.───他们还测量到达格兰·萨索的中微子的时间分布。
The Gran Sasso team's result is six standard deviations.───而格朗萨索研究组的结果是六个标准差。
The old beam was created by smashing long bunches of protons into a target to produce neutrinos, which would then travel on to Gran Sasso.───过去的中微子束由长串质子轰击靶标产生,之后发射到格朗萨索。
The prediction had been posted weeks earlier by a seismologist at the Gran Sasso National Laboratory in Abruzzi, Italy.───该预告是在数周前由意大利阿布鲁齐的巨石峰国家实验室的地震学家发布的。
With the beam tightened up, the neutrinos still arrived at Gran Sasso 60 nanoseconds faster than light would have.───随着中微子束的收紧,中微子仍然比光提早了60纳秒抵达了格兰萨索。
Dr Bertolucci, the director of research at Cern, told BBC News: "In the last few days we have started to send a different time structure of the beam to Gran Sasso.
Will the Gran Sasso result embarrass the know-it-all physicists, knock them off their pedestals by showing how wrong they have been all along?
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.
Gran Sasso to the north is the highest peak in the Apennine range, and a cable-car runs up to Campo Imperatore.
The heavy spending, which included $ 108, 000 for John R.. Sasso, former chief of staff to Gov.
