Abstract

We performed an improved search for νμ → νe oscillation with the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment, using the full data sample of 9.2 × 1019 protons on target. No evidence for a νe appearance signal was found, and we set bounds on the νμ → νe oscillation parameters. At Δm2 = 2.8×10−3 eV2, the best fit value of the K2K νμ disappearance analysis, we set an upper limit of sin2μe < 0.13 at 90% confidence level.
