研究概要	1.ニュートリノ宇宙物理と宇宙線(佐藤・長滝) ニュートリノ質量階層構造が電子、ミューオン、タウオンとは逆の場合の超新星背景ニュートリノのフラックスを計算し、スーパーカミオカンデで検出することにより1-3の混合角パラメータや質量の2乗差に関して制限が付けられることを示した。又、中性子星から放出される高エネルギー宇宙線は超新星残骸との相互作用により、高エネルギーニュートリノとして観測される可能性を指摘した。 2.多次元宇宙の進化とブレーン世界説(佐々木・白水) ブレーン宇宙論におけるバルク・インフラトンモデルにおいて、密度揺らぎを解析し、低エネルギー極限で4次元理論が完全に再現されることを示した。また、ガウス・ボンネ理論では余剰次元が約10kmという大きなサイズになり得ることを示した。又、Dブレーンにもとづいたブレーン宇宙論の基礎研究を行った。特に、ブレーン上の重力理論の導出を行い、宇宙項の存在の深い示唆を得た。 3.物質・反物質の非対称性の起源とインフレーション理論(吉村・川崎・柳田) 超対称性理論に基づくSUSY Breaking機構に伴って引き起こされるレプトン非対称性を調べ、現在の宇宙に於けるレプトン非対称の程度を説明出来ることを示した。又、最近発表された宇宙背景放射のデータに基づいて、ハイブリッド・インフレーション宇宙モデルの構築、カーバトン・モデルにおける等曲率揺らぎの生成と制限、大質量星による宇宙の再イオン化を調べた。 4.観測による初期宇宙理論モデルの検証(須藤・樽家) SDSSの銀河サーベイデータから、ミンコフスキー汎関数・3点相関関数を計算し、銀河分布の非ガウス性の存在とその性質を調べた。また、宇宙のダークバリオン探査専用衛星DIOSの提案とその科学的可能性を検討した。又、宇宙大規模構造に現れる非ガウス的な性質について解析し、質量密度ゆらぎの分布関数に現れる対数正規的な性質が、自己重力天体の密度構造と密接に関係していることを示した。
