Outline of Final Research Achievements

We performed R&D of sterile-neutrino (4th neutrino that is not included in the standard model of elementary particles) detector. The R&D subjects were, development of liquid scintillator, conceptual design of the detector structure and various tests, preparation of electronics for signal read out, etc. Based of the R&D results, the JSNS2 neutrino detector was constructed and we successfully took initial data using the real beam at J-PARC MLF in June 2020.

Academic Significance and Societal Importance of the Research Achievements

本研究のニュートリノ検出器R&Dの結果を元にしてステライルニュートリノ検出器の制作が行われ,最初のデータ収集を行うことに成功した.今後高い信頼性でステライル ニュートリノ探索を行うことが可能となった.
ステライルニュートリノは素粒子の標準理論には含まれていない,弱い相互作用を行わない第4のニュートリノである.もしステライルニュートリノが発見されれば,これまでの常識を覆す非常に大きな学術的インパクトを素粒子物理に与え,我々の自然に対する理解を深めることになる.
