Measurement of Neutrino Oscillations with the MINOS Detectors in the NuMI Beam

(G. J. Feldman is the Harvard author) This Letter reports new results from the MINOS experiment based on a two-year exposure to muon neutrinos from the Fermilab NuMI beam. Our data are consistent with quantum-mechanical oscillations of neutrino flavor with mass splitting |delta m^2|=(2.43±0.13)×10^-...

Zusammenfassung:(G. J. Feldman is the Harvard author) This Letter reports new results from the MINOS experiment based on a two-year exposure to muon neutrinos from the Fermilab NuMI beam. Our data are consistent with quantum-mechanical oscillations of neutrino flavor with mass splitting |delta m^2|=(2.43±0.13)×10^-3 eV^2 (68% C.L.) and mixing angle (sin(2*theta))^2>0.90 (90% C.L.). Our data disfavor two alternative explanations for the disappearance of neutrinos in flight: namely, neutrino decays into lighter particles and quantum decoherence of neutrinos, at the 3.7 and 5.7 standard-deviation levels, respectively.
