通过比较 MINOS 实验中相距 734 公里的近端和远端探测器的探测时间，测量了 ~3 GeV 中微子束的速度。总共使用 473 个远探测器中微子事件来测量 (v-c)/c=5.12.910-5（68% C.L.）。通过将 258 个带电中微子事件的测量能量与其到达远处探测器的时间相关联，对中微子质量施加 mnu<50 MeV/c2 (99% C.L.) 的限制。
The velocity of a ~3 GeV neutrino beam is measured by comparing detection times at the near and far detectors of the MINOS experiment, separated by 734 km. A total of 473 far detector neutrino events was used to measure (v-c)/c=5.12.910-5 (at 68% C.L.). By correlating the measured energies of 258 charged-current neutrino events to their arrival times at the far detector, a limit is imposed on the neutrino mass of mnu<50 MeV/c2 (99% C.L.).
