First MINOS Results with the NuMI Beam

The results from the initial exposure of the MINOS detectors to neutrinos produced by the Fermilab NuMI beam are reported here. The exposure consisted of 1.27×1020 120 GeV protons incident on the NuMI target. The data show the observation of 215 neutrinos with energies below 30 GeV while 336±14.4 events were expected. The data are consistent with νμ disappearance via neutrino oscillations with and sin22θ23>0.87 (68% C.L.).
