Summary
We have measured the rates and spectra of neutral-current neutrino interactions in the MINOS detectors, which are separated by 734 km. A depletion in the rate at the far site would indicate mixing between ν{sub μ} and a sterile particle. The depletion of the total neutral-current event rate at the far site is limited to be below 17% at 90% confidence level without ν{sub e} appearance. Assuming oscillations occur at a single mass-squared splitting, a fit to the neutral- and charged-current energy spectra shows the fraction of ν{sub μ} oscillating to a sterile neutrino is 0.28{sub -0.28}{sup +0.25}(stat.+syst.). Including ν{sub e} appearance at the current experimental upper bound limits the depletion to be below 21% at 90% confidence level and the fit fraction of ν{sub μ} oscillating to a sterile neutrino is 0.43{sub -0.27}{sup +0.23}(stat.+syst.).
