| Outline of Final Research Achievements |
Superstring theory is considered to be the most promising candidate for the unified theory of elementary particles including gravity. In order to construct viable models of elementary particles using superstring theory, we need to understand the so-called "nonperturbative effects" of the superstring theory. String field theory is supposed to be the most promising approach to study such effects of superstring theory. The goal of this project is to study superstring theory using the string field theory. In this project, we have
1. solved the contact term problem and constructed a supsertring field theory using the light-cone gauge approach
2. obtained classical solutions of string field theories

| Academic Significance and Societal Importance of the Research Achievements |
現在の素粒子理論における最大の目標の一つは、重力の量子論を理解することである。量子力学は現在の我々の日常生活で出会う様々なテクノロジーの基礎となっている。また、重力は我々にとって最も身近な力である。残念ながら、今のところ重力を量子力学の枠組みで理解することができていない。本研究の結果はこの大目標への一歩となっている。このような研究は遠い未来のテクノロジーを支える基礎になる可能性がある。
