The Results of Oscillation Analysis in K2K Experiment And An Overview of JHFnu Experiment
Abstract
Description
This paper presents the results of oscillation analysis in K2K experiment. The results show indications of neutrino oscillation and give a new constraint on the oscillation parameters. The difference of neutrino masses squared $Δm^2$ lies between 1.5 and 3.9$\times10^{-3} {\rm eV}^2$ at $\sin^2 2θ=1$ with the confidence level of 90%. In addition to these results, a brief overview of future long-baseline neutrino experiment in Japan, JHF-$ν$ experiment, is also given in this paper.
