Measurement of neutrino velocity with the MINOS detectors and NuMI neutrino beam

The velocity of a similar to 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 (nu - 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.).
