Resum:	We present results for νμ oscillation in the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment. K2K uses an accelerator-produced νμ beam with a mean energy of 1. 3 GeV directed at the Super-Kamiokande detector. We observed the energy-dependent disappearance of νμ, which we presume have oscillated to ντ. The probability that we would observe these results if there is no neutrino oscillation is 0. 0050% (4. 0σ).
