Study of muon neutrino disappearance using the Fermilab Main Injector
neutrino beam

Αγγλικά

We report the results of a search for nu(mu) disappearance by the Main
Injector Neutrino Oscillation Search [D. G. Michael (MINOS), Phys.
Rev. Lett. 97, 191801 (2006).]. The experiment uses two detectors
separated by 734 km to observe a beam of neutrinos created by the
Neutrinos at the Main Injector facility at Fermi National Accelerator
Laboratory. The data were collected in the first 282 days of beam
operations and correspond to an exposure of 1.27x10(20) protons on
target. Based on measurements in the Near Detector, in the absence of
neutrino oscillations we expected 336 +/- 14 nu(mu) charged-current
interactions at the Far Detector but observed 215. This deficit of
events corresponds to a significance of 5.2 standard deviations. The
deficit is energy dependent and is consistent with two-flavor neutrino
oscillations according to |Delta m(2)|=2.74(-0.26)(+0.44) x 10(-3)
eV(2)/c(4) and sin(2)2 theta > 0.87 at 68% confidence level.
