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 $Delta m^2$ lies between 1.5 and 3.9$times10^{-3} {rm eV}^2$ at $sin^2 2theta=1$ with the confidence level of 90%. In addition to these results, a brief overview of future long-baseline neutrino experiment in Japan, JHF-$ u$ experiment, is also given in this paper.
The KLOE detector at the DA$Phi$NE $phi$-factory has been operating in two periods from 2001 to 2006 and from 2014 to 2018 collecting a large sample of $phi$-meson decays. This allowed to perform precision measurements and studies of fundamental symm
The $ uebar$ flux and spectrum have been measured at a distance of about 800 m from the reactors of the Palo Verde Nuclear Generating Station using a segmented Gd-loaded liquid scintillator detector. Correlated positron-neutron events from the reacti
The TRIUMF Weak Interaction Symmetry Test (TWIST) experiment was designed to test the standard model at high precision in the purely leptonic decay of polarized muons. A general four-fermion interaction model is used to describe the muon decay. TWIST
The analysis and results are presented from the complete data set recorded at Palo Verde between September 1998 and July 2000. In the experiment, the $ uebar$ interaction rate has been measured at a distance of 750 and 890 m from the reactors of the
A muon range detector (MRD) has been constructed as a near detector for the KEK-to-Kamioka long-baseline neutrino experiment (K2K). It monitors the neutrino beam properties at the near site by measuring the energy, angle and production point of muons
