| Research Abstract |
The motivation of this research is to search for new physics beyond the standard model by the world's first measurement of the very rare decay, K→π0νν-. The experiment has been performed by high intensity proton beam at J-PARC. We constructed an electro-magnetic calorimeter composed of the CsI crystal as a main detector and evaluated the performance using the beams. The experiment is delayed about 1 year due to the Grate East Japan Earthquake, however, we have started to accumulate the physics data.
