Abstract

This paper reports measurements of atmospheric neutrino and antineutrino interactions in the MINOS Far Detector, based on 2553 live-days (37.9kton-years) of data. A total of 2072 candidate events are observed. These are separated into 905 contained-vertex muons and 466 neutrino-induced rock-muons, both produced by charged-current ν _μ and ν _̄μ interactions, and 701 contained-vertex showers, composed mainly of charged-current ν _e and ν _̄e interactions and neutral-current interactions. The curvature of muon tracks in the magnetic field of the MINOS Far Detector is used to select separate samples of ν _μ and ν _̄μ events. The observed ratio of ν _̄μ to ν _μ events is compared with the MonteCarlo (MC) simulation, giving a double ratio of Rν̄/νdata/ Rν̄/νMC=1.03±0.08(stat)±0.08(syst). The ν _μ and ν _̄μ data are separated into bins of L/E resolution, based on the reconstructed energy and direction of each event, and a maximum likelihood fit to the observed L/E distributions is used to determine the atmospheric neutrino oscillation parameters. This fit returns 90% confidence limits of |Δm2|=(1.9±0.4)×10 ^-3eV2 and ^sin22θ>0.86. The fit is extended to incorporate separate ν _μ and ν _̄μ oscillation parameters, returning 90% confidence limits of |Δm2|-|Δm ^̄2|=0.6- 0.8+2.4×10 ^-3eV2 on the difference between the squared-mass splittings for neutrinos and antineutrinos.
