Indications of neutrino oscillation in a 250 km long-baseline experiment

…, S Nakayama, T Namba, K Nishikawa, S Nishiyama… - Physical Review Letters, 2003 - APS
The K2K experiment observes indications of neutrino oscillation: a reduction of ν μ flux
together with a distortion of the energy spectrum. Fifty-six beam neutrino events are …

Measurement of neutrino oscillation by the K2K experiment

…, S Nawang, K Nishikawa, H Nishino, S Nishiyama… - Physical Review D, 2006 - APS
We present measurements of ν μ disappearance in K2K, the KEK to Kamioka long-baseline
