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.久吾，与M. Bando考虑了新的多夸克束缚态，如使用5d超引力的五夸克，并开发了计算这些状态质量的方法。他还计算了电子和“电子”的电和磁偶极矩。Bando和M. Tanimoto等人也研究了用零元对称矩阵模型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味对称性的模型，构造了几个能实际解释夸克和轻子混合和质量矩阵的模型。柳田提出了一个理论，认为我们宇宙的重子数实际上是通过超重的马约拉纳型费米子衰变产生的。他还写了一篇关于瘦生论的评论论文。小林开始系统地分析超弦理论的味道结构。他研究了测定. ...更多信息 模场和自发超对称破缺。Maekawa在一个具有“E6和水平对称性”的模型中发现，CP对称性的自发破缺也解决了严重的超对称CP问题，正确地解释了Kobayashi-Maskawa相位。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，也会给出一个自发的超对称性破缺机制。Sugimoto和T. Sakai等人在超弦理论的基础上构造了一个新的全息QCD模型。我们还实现了本研究项目的另一个重要目标，即在这四年中，我们每年都举办夏季研究所，作为组织和开展这一领域全国性合作研究的核心场所。事实上，2006年在韩国浦项举办的暑期学院已经成为亚洲国际合作的核心。少
