The result , published in arxiv , an online database , is based on data from 15000 neutrinos detected at gran sasso over three years .
这一公布在网上数据库arxiv上的结果来源于过去三年格兰萨索接收到的15000个中微子数据。
Individual neutrinos received at gran sasso could have come from protons early or late in the proton pulse , creating uncertainty in their exact travel time , detractors said .
The gran sasso national laboratory of the italian institute of nuclear physics , located nearly a mile below the surface of the gran sasso mountain about 60 miles outside of rome , detects tiny particles called neutrinos .
And in a cavern in gran sasso in italy the highest part of the apennines an experiment is looking at another oscillation that between muon - and tau-neutrinos .
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。
For instance , when a neutrino strikes the detector in gran sasso , that signal has to travel 8km through a waveguide before a timing measurement can be made .
例如,当一个中微子击中格朗萨索的检测器后,该信号必须通过波导管传送8公里方能进行时间测量。
The italian institute for nuclear physics ( infn ) , which runs the gran sasso lab , has just confirmed the earlier result based on a re-examination of the old data .
管理格朗萨索实验室的意大利核物理研究所重新检查了过去的数据,再次确认了早先的结果。
Dining is now top-notch nightlife exhilarating and this year also marks the inauguration of the tallest building on the continent the 70-storey torre gran costanera .
