キーワード	場の量子論 / 自発的対称性の破れ / 電弱理論 / 格子ゲ-ジ理論 / ヒッグス機構 / ワインバ-グ・サラム模型 / 量子電気力学 / 共形場理論
研究概要	初年度の研究成果をふまえ、さらにそれを発展させるために、次のような具体的な問題について重点的に作業を行った。 1.数値シミュレ-ションによるゲ-ジ場理論の相構造の研究 2.電弱理論のヒッグス機構に対する具体的な動的模型の構築 3.電弱理論の非摂動解(インスタントン、スファレロンなど)によるバリオン数非保存現象の研究 4.共形場理論の臨界点外で誘導される2次元重力の行列模型による研究 5.低エネルギ-現象における複合模型の検証 6.ヒッグス場の強結合相の解析的取り扱いこれらの研究の結果、いくつかの注目に値する進展が見られた。 1.格子されたコンパクト及び非コンパクト量子電気力学の相構造の間に関係をつけることができ、ある種の対応関係があることがわかった。 2.紐理論で現れる反対称テンソルと閉じ込め機構との関係が、行列模型を使った数値シミュレ-ションによって明らかになった。 3.未だ発見されていないトップクォ-クの質量に対する予言が、ヒッグス粒子の複合模型のとり方によって変わり得ることが示された。 4.シュビンガ-・ダイソン方程式を用いてヒッグス場の強結合相の性質が解明された。 5.複合模型の痕跡が、低エネルギ-現象でも、標準模型の輻射補正と同程度の大きさで検知でき、実験的検証の可能性があることがわかった。これらの研究は、このまま来年度へもつなげていきたい。
