Outline of Annual Research Achievements

濱口は、Minimal gauged U(1)Lmu-Ltau模型の熱的レプトジェネシスの解析を行った。
濱口は、ミューオンg-2アノマリーを超対称性模型で説明する際に仮定される、軽いsleptonがAffleck-Dineレプトジェネシスに与える影響を議論した。
松本は、媒介粒子が同じ量子数を持つ特定の標準模型粒子と縮退している際に、両者間の相互作用(と媒介粒子の質量の積)と縮退する粒子の崩壊幅の大小に応じて、媒介粒子の崩壊幅をどのように計算するべきかを定量的に明らかにした。
長峯は、初代銀河における巨大ブラックホールの種の形成に関する宇宙論的輻射流体シミュレーションを実施し、輻射フィードバックの重要性について議論した。また、原始銀河団、大質量銀河の形成に伴う物質降着や金属汚染について、磁気流体の効果も取り入れて吟味した。
Melia developed a framework in which dark matter can be explained by relic structure in the theory of general relativity, explored possible search strategies including potential signals of a predicted charged component in underground detection experiments.
柳田は、最近Nanogravで発見された重力波backgroundがaxion-curvaton模型で説明できるかを検討した。
