Abstract

MINOS records interactions of neutrinos produced by the Fermilab NuMI beam line in two detectors, 734 km apart. Comparisons of the energy spectra and beam composition at the two sites yield precision measurements of neutrino oscillations for L/E∼500 km/GeV. In this paper, updated results from an integrated exposure more than twice that of earlier publications will be presented. We will present a measurement of the probability of muon-neutrino disappearance as a function of energy and of the neutrino oscillation parameters and sin2(2θ23). We will report on the measurement of neutral current interaction rates in each detector, which enables a search for light neutrino families that do not couple via the weak interaction. We will also discuss results from the search for electron-neutrino events in the Far Detector, which probes the value of the mixing angle θ13. Finally, we will discuss a dedicated antineutrino run, which allows for measurement of antineutrino oscillation parameters.
