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

The authors report the results of a search for νe appearance in νμ beam in the MINOS long-baseline neutrino experiment. With an improved analysis and an increased exposure of 8.2 x 1020 protons on the NuMI target at Fermilab, they find that 2 sin223 sin213) < 0.12 (0.20) at 90% confidence level for δ = 0 and the normal (inverted) neutrino mass hierarchy, with a best fit of 2 sin2θ23) sin 2 (2θ13) = 0.041-0.031 +0.047 (0.079-0.053 +0.071). The θ13= 0 hypothesis is disfavored by the MINOS data at the 89% confidence level.
