Description
ダークマターの正体は何か？ - 広大なディスカバリースペースの網羅的研究
"What is dark matter? - Comprehensive study of the huge discovery space in dark matter"
Date: March 7 - 9, 2023
Format: hybrid
Venue: Lecture Hall, Kavli IPMU plus Zoom
Overview:
ダークマターはその存在が確実であり、宇宙の星や銀河を作った立役者だが、その正体は不明である。今までは素粒子物理学の要請から、約二桁の質量範囲のWIMPパラダイムに研究が集中していたが、2010年代の実験・観測で制限が厳しくなり、WIMP以外の候補への関心が高まっている。本研究領域では、ダークマターの質量で90桁にわたる広大なディスカバリースペースを網羅的にカバーするため、今までにない多角的な方法で理論から宇宙観測・地上実験にまたがる研究領域を拓くことを目指す。近年急速に技術が成熟したレーザー干渉計や、すばる観測・加速器・人工衛星 ・重力波・高エネルギーニュートリノを含むタイムリーな実験・観測を用いた研究を展開する。特に、日本が投資してきた既存の最先端施設を有効活用し、若手研究者のユニークなアイデアによって工夫を加えることでインパクトのある研究成果を導出することを目指す。天文学・物理学・工学の分野において融合的で飛躍的な研究の展開・開拓することを目指す。
本シンポジウムでは、各計画研究グループの研究、研究期間中 (R2-R6年度) に目指すゴール、F2021年度までの進捗状況を紹介する。
“Dark matter” certainly exists and plays a crucial role in formation of all cosmic structures such as galaxies. However, the nature of dark matter remains a mystery. As guided by particle physics, most efforts of dark matter search have been focused on Weakly Interacting Massive Particles (WIMP) candidates in the mass range of two order magnitudes, but observations and experiments in 2010’s did not find any clue of WIMP. There is now growing interest in non-WIMP dark matter candidates. In this research area, to comprehensively cover the vast discovery space of dark matter search spanning 90 orders of magnitudes in the mass scale, we aim at opening up research area using theoretical approaches, observations of the Universe and terrestrial experiments. Observation and experimental research groups will explore the nature of dark matter using new methods based on the unique idea/consideration from this research group and taking advantage of the cutting-edge observational data of the Universe.
At this online symposium, we would like to introduce the goal of this research program, and each research group will introduce the goals and current status of the research (FY2020-2024).

invited talk: Particle physics models that predict dark matter in the form of primordial black holes
Primordial black hole is a dark matter candidate in a variety of existing models of physics beyond the standard model, including supersymmetry models and models with asymmetric dark matter. I will review the formation of black holes in such scenarios, as well as the effects of predicted PBHs on astrophysics and cosmology.
