项目摘要

T. Kugo, with M. Bando, considered new multi-quark bound states like penta-quarks using 5d supergravity and developed the computing method for masses of those states. He also calculated the electric and magnetic dipole moments of monopole and 'electron'.M. Bando, together with M. Tanimoto, also studied the possibility explaining neutrino mass matrix unifiedly with those of quarks and leptons in a category of models with a symetric matrix with zero elements.M Tanimoto considered models which possess various discrete flavor symmetries, and constructed several models which can actually explain mixings and mass matrices of quark and leptons.T. Yanagida proposed a theory of leptogenesis in which baryon number of our Universe is in fact generated through the decay of superheavy Majorana-type fermions. He also wrote a review paper on leptogenesis theory.T. Kobayashi started a systematic analysis of the flavor structures resulting from superstring theory. He stu died the mechanism for determin … More ing the moduli fields and spontaneous supersymmetry breaking.N. Maekawa found in a model with "E6 and horizontal symmetry" that a spontaneous breaking of CP symmetry resolves also the serious Supersymmetric CP problem explaining the Kobayashi-Maskawa phase properly. He also showed that his unified model with anomalous U(1) symmetry, if modified slightly, also gives a spontaneous supersymmetry breaking mechanism.S. Sugimoto, together with T. Sakai, constructed a novel holographic QCD model based on the superstring theory. They showed that the model can reproduce various properties of hadrons in our real world.We also achieved another big aim of this research project; namely we held the summer institute every year f or this four years as a core place where nation-wide cooperative researches in this field are organized and carried out. In fact, as shown by the fact that the Summer Institute in 2006 was held at Pohang in Korea, this Summer Institute is now becoming even a core of international collaborations in Asia. Less

T. Kugo 和 M. Bando 使用 5d 超引力考虑了新的多夸克束缚态，如五夸克，并开发了这些态质量的计算方法。他还计算了单极子和“电子”的电偶极矩和磁偶极矩。 Bando 和 M. Tanimoto 还研究了在零元素对称矩阵模型中统一解释中微子质量矩阵与夸克和轻子质量矩阵的可能性。M Tanimoto 考虑了具有各种离散风味对称性的模型，并构建了几个能够真正解释夸克和轻子混合和质量矩阵的模型。柳田提出了轻子发生理论，其中宇宙的重子数实际上是通过超重马约拉纳型费米子的衰变产生的。他还写了一篇关于轻子发生理论的评论论文。小林开始对超弦理论产生的风味结构进行系统分析。他研究了确定模场和自发超对称破缺的机制。 Maekawa 在“E6 和水平对称”模型中发现，CP 对称性的自发破缺也解决了严重的超对称 CP 问题，正确解释了小林-益川相。他还表明，他的具有反常 U(1) 对称性的统一模型，如果稍加修改，也能给出自发的超对称破缺机制。 Sugimoto 与 T. Sakai 一起构建了一种基于超弦理论的新型全息 QCD 模型。他们表明该模型可以再现现实世界中强子的各种特性。我们还实现了这个研究项目的另一个大目标：就是这四年我们每年都举办暑期学院，作为全国范围内组织开展该领域合作研究的核心场所。事实上，正如2006年在韩国浦项举办的暑期学院所表明的那样，该暑期学院现在甚至正在成为亚洲国际合作的核心。较少的
