Title: Improved search for muon-neutrino to electron-neutrino oscillations in MINOS

Abstract

The authors report the results of a search for ν e appearance in ν μ beam in the MINOS long-baseline neutrino experiment. With an improved analysis and an increased exposure of 8.2 x 10 20 protons on the NuMI target at Fermilab, they find that 2 sin 223 sin 213) < 0.12 (0.20) at 90% confidence level for δ = 0 and the normal (inverted) neutrino mass hierarchy, with a best fit of 2 sin 2θ 23) sin 2 (2θ 13) = 0.041 -0.031 +0.047 (0.079 -0.053 +0.071). The θ 13= 0 hypothesis is disfavored by the MINOS data at the 89% confidence level.
