The first results of the K2K(KEK to Kamioka) long-baseline neutrino oscillation experiment are presented in this talk. In 1999 7.2x10^18 protons on target were delivered to the experiment. During this period of running there were 3 events…
The latest results of the K2K experiment are reported. The results are based on data taken from June, 1999, to June, 2000, corresponding to a total $2.6 \cdot 10^{19}$ protons on target. Twenty seven fully-contained events in the 22.5 kton…
The KEK-to-Kamioka long-baseline neutrino experiment (K2K) has begun its investigation of neutrino oscillation, and has established the method of a long-baseline neutrino experiment. From the first 100 days of data-taking, a deficit of muon…
The K2K Long--Baseline neutrino oscillation experiment has been aquiring data since mid-1999 and has analysed those up to March of 2001. Forty-four fully contained events are observedin the fiducial volume of the far detector where…
The KEK to Kamioka long-baseline neutrino experiment (K2K) is the first accelerator-based experiment with hundreds of km neutrino path length. K2K focuses on the study of the existence of neutrino oscillations in $\nu_{\mu}$ disappearance…
The KEK to Kamioka long-baseline neutrino experiment (K2K) has begun its investigation of neutrino oscillations suggested by atmospheric neutrino observations. Twenty-eight neutrino events have been detected in coincidence with the expected…

New results from the K2K (KEK to Kamioka) long-baseline neutrino-oscillation experiment is presented.
The latest results from K2K experiment are reported, with focus on muon neutrino oscillation. The results are based on data taken from June 1999 to February 2004, corresponding to 8.9 x 10^19 protons on target.
A long-baseline neutrino-oscillation experiment using a well-defined neutrino beam is in preparation at KEK. Neutrinos generated at KEK will be detected by the Super-kamiokande detector 250 km away. The design of the neutrino beam line,…
We performed an improved search for $\nu_\mu \to \nu_e$ oscillation with the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment, using the full data sample of $9.2 \times 10^{19}$\xspace protons on target. No evidence for a…
T2K is a long baseline high intensity neutrino oscillation experiment employing an off-axis design to search for the as yet unobserved appearance of \nu_e neutrinos in a \nu_{\mu} beam. The neutrino beam originates at the J-PARC facility in…
We present measurements of nu_mu disappearance in K2K, the KEK to Kamioka long-baseline neutrino oscillation experiment. One hundred and twelve beam-originated neutrino events are observed in the fiducial volume of Super-Kamiokande with an…
We present results for muon neutrino oscillation in the KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment. K2K uses an accelerator-produced muon neutrino beam with a mean energy of 1.3 GeV directed at the Super-Kamiokande…
The Tokai-to-Kamioka (T2K) long-baseline neutrino-oscillation experiment is being prepared for start of operations in Fall 2009. The purpose of T2K is to measure the oscillation parameters from an intense muon neutrino beam. In order to…
The K2K experiment observes indications of neutrino oscillation: a reduction of $\nu_\mu$ flux together with a distortion of the energy spectrum. Fifty-six beam neutrino events are observed in Super-Kamiokande (SK), 250 km from the neutrino…
During the first half of the K2K run, data corresponding to 4.8x10^19 POT were accumulated. In this data set, 56 accelerator-produced neutrino events were observed in the far detector, while the expected number from the near site…
We briefly discuss the impact of initial data from the KEK-to-Kamioka (K2K) neutrino experiment on the nu_mu-->nu_tau oscillation parameters (m^2,tan^2 psi) currently indicated by the Super-Kamiokande (SK) atmospheric neutrino experiment.…
The Tokai to Kamioka (T2K) experiment is a next generation long baseline neutrino oscillation experiment utilising the Japan Proton Accelerator Research complex (J-PARC) high intensity proton synchrotron. After a brief introduction of the…
The proposed KAON factory at the Triumf Laboratory in Vancouver, Canada provides a unique opportunity for high statistics long baseline neutrino oscillation experiments. Several possibilities are under active consideration. In this paper we…
