Abstract

原子炉の運転により生成されるニュートリノは,通常では無用なものとして無視されているが,ニュートリノ研究の世界では,その初期から重要な役割を果たしてきた.今またその利用により新たな成果を得ることを目指して,世界各地で多くの実験が計画されている.それが,ここで紹介する原子炉による未だ測定値が得られていないニュートリノ混合角θ_<13>の精密測定である.

Despite its extremely small reaction probability and difficulty of its detection, the reactor neutrinos have been playing a significant roles in elementary particle physics since its early days. Recently, new reactor neutrino oscillation experiments, which aim to discover the last neutrino mixing angle θ_<13>, are being planned worldwide. These experiments are complementary to accelerator based neutrino oscillation experiments and by combining both experiments, precious measurements will become possible. In this article, significance of these new-generation reactor-neutrino experiments, as well as recent world activities are described.
