Outline of Final Research Achievements

Astronomical observations suggest that there are about five times more substances called "dark matter" in the universe than ordinary matter (galaxies, etc.), but their identity is a complete mystery. Direct detection of this dark matter is one of the greatest challenges of current particle physics and astrophysics. In this study, we searched for the dark matter using a liquid argon detector.

Academic Significance and Societal Importance of the Research Achievements

暗黒物質の直接検出は素粒子物理学における重要課題のひとつであるが、予想される信号は非常に微弱なため、高性能の検出器開発がカギとなる。優れた粒子識別能力を持つ液体アルゴン検出器は、近年素粒子宇宙物理学実験分野において開発が著しく進んでいる。本研究では暗黒物質直接探索のためにこの液体アルゴン検出器の性能をさらに向上させるための開発を行った。
