Bishai, et al. 2011. “Improved Search for Muon-Neutrino to Electron-Neutrino Oscillations in MINOS.” Physical Review Letters 107 (18) (October). doi:10.1103/physrevlett.107.181802.0031-9007http://nrs.harvard.edu/urn-3:HUL.InstRepos:34334615We report the results of a search for νe appearance in a νμ beam in the MINOS long-baseline neutrino experiment. With an improved analysis and an increased exposure of 8.2×1020 protons on the NuMI target at Fermilab, we find that 2sin2(θ23)sin2(2θ13)<0.12(0.20) at 90% confidence level for δ=0 and the normal (inverted) neutrino mass hierarchy, with a best-fit of 2sin2(θ23)sin2(2θ13)=0.041+0.047−0.031(0.079+0.071−0.053). The θ13=0 hypothesis is disfavored by the MINOS data at the 89% confidence level.en-USneutrino: mass: hierarchyMINOSneutrino: oscillationneutrino/mu: beamneutrino/e: particle identificationneutrino: mixing angleexperimental resultsFermilabJournal Article2017-11-0710.1103/PhysRevLett.107.181802
