Improved search for Muon-neutrino to electron-neutrino oscillations in MINOS. Academic Article uri icon

abstract

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