高密度物質中での軸性アノマリーの運命: 2カラーQCDという仮想世界からの究明

QCDでは、「軸性アノマリー」と呼ばれる量子的"異常"が発現することが知られており、この"異常"がハドロンに作用する機構はよく理解されている。一方高温・高密度系という「極限系」で、この"異常"がどのようにハドロンに作用するのか、その全容は謎に包まれたままである。本研究では、モンテカルロ数値シミュレーションが可能な「2カラーQCD」という仮想的な世界に着目し、ハドロン有効理論と汎関数繰込み群を用いて、極限系で軸性アノマリーがハドロンに及ぼす効果の究明を進める。本研究は、中性子星内部でのクォーク-ハドロン連続的転移や、η'中間子原子核の存在可能性など、多彩な情報を与えることに繋がる。

2023年度は、研究課題として挙げた(1) クォーク自由度によるバリオン-クォーク物質転移の直接的な記述、 (2) その応用としての「ハイペロン問題」の解明、(3) 非摂動的グルーオン伝搬関数を基底に取った新しい有限密度摂動論の構築、 の研究課題のうち、特に(1)と(2)について集中的に研究を行った。特に、バリオンークォーク物質転移の機構を明快にする可解なクォーク・ハドロン双対模型を藤本、McLerran氏と共に構築した。この双対模型は、バリオン自由度による記述とクォーク自由度による記述に１体１対応の関係がつけられ、クォーク・ハドロン・クロスオーバー領域のような自由度が不明瞭な領域で特に有効である。この可解模型を解くことで、中性子星状態方程式の文脈で有名なMcLerran-Reddy模型の基礎づけを行なうことができた。特に、ハドロン物質からクォーク物質に向かうにつれて何故状態方程式が『硬く』なるのかを、クォークに対するパウリ原理と相対論的運動学という基本的な性質から説明することができた。現在は、この仕事を拡張しハイペロン問題を解析中である。
また、末永氏、千葉氏と有限アイソスピン密度の系をクォークメソン模型と呼ばれるクォーク自由度とメソン自由度を含む模型で解析した。この系では、格子QCDシミュレーションの結果があるので、その結果と模型計算との比較を行ないながら、有限密度系の概念をテストすることができる。我々は特にクォーク・ハドロン・クロスオーバーの概念がもたらす物理について、第一論文でゼロ温度の場合、第二論文で有限温度の場合を解析した。大きな成果は、ハドロン自由度が空間的に重なる約半分程度の密度でクォーク自由度が重要であることを示し、それが状態方程式の硬化に効いていることを示したことである。
以上の研究に関連して、国際会議にて４つの招待講演、国内研究会・セミナーを５回行った。
