Outline of Final Research Achievements |
We developed the new scheme to determine the neutrino mass using the torsion-bar antenna and high power neutrino beam generated at J-PARC. Neutrino beam can transfer its momentum to the torsion-bar antenna as force vis neutral current interaction. Using the realistic parameter, we found that measurements of the neutrinos mass is much difficult using this scheme. Thus, we designed the new torsion-bar antenna based on cryogenically-cooled metal suspension. In addition, we set the new upper limits on gravitational wave background for 35-830mHz.
