Abstract

We present results for

ν_{μ}

oscillation in the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment. K2K uses an accelerator-produced

ν_{μ}

beam with a mean energy of 1.3 GeV directed at the Super-Kamiokande detector. We observed the energy-dependent disappearance of

ν_{μ}

, which we presume have oscillated to

ν_{τ}

. The probability that we would observe these results if there is no neutrino oscillation is 0.0050% (

4.0 σ

).
