Measurement of neutrino velocity with the MINOS detectors and NuMI neutrino beam
arXiv:0706.0437 · doi:10.1103/PhysRevD.76.072005
Abstract
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 = 5.1 +/- 2.9 x 10^-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 m_nu < 50 MeV/c^2 (99% C.L.).
