Ito studied the effects of the Ramond-Ramond background in supersymmetric gauge theory as an low-energy effective one on the D-branes in superstring theory. We found the following new results: (1) It is known that the effects of the graviphoton background appears as the non(anti) cnmmutativity on the worldvolume of the D-brane. We calculated the graviphoton effects in N=2 and N=4 supersymmtric Yang-Mills theory from the superstring theory and showed that the deformed terms in the Lagrangian agrees with the field theory results. (2) We classified the R-R backgrounds systematically and found the new deformation which cannot be obtained by the non(anti)commutative superspace. (3) We found new noncommutative deformation of supersymmetry algebra in N=2 super Yang-Mills theory in the graviphoton background. (4) We found new scalar potential deformed by the R-R background and vacuum represented by the fuzzy sphere.Inami applied the idea of AdS/CFT correspondence and holography to QCD and proposed new model for baryons. He investigate new types of non-linear sigma model in non(anti)commutative superspace and its renormalization.

ITO研究了Ramond-Ramond背景在超对称量表理论中的影响，这是对SuperString理论中D型桥梁的低能量有效性。我们发现了以下新结果：（1）众所周知，势力背景的影响似乎是非（抗）cnmmutitivity对D-Brane世界伏洛的影响。我们计算了n = 2和n = 4 supersymmtric yang-mills理论中的重力体效应，并表明拉格朗日人中的变形术语与现场理论的结果一致。 （2）我们系统地对R-R背景进行了分类，并发现了非（反）交换超级空间无法获得的新变形。 （3）我们在急剧背景中发现了n = 2超级阳米尔斯理论中超对称代数的新的非交通性变形。 （4）我们发现由模糊球体表示的R-R背景和真空变形的新标量势变形。Inami将AD/CFT对应关系和全息图应用于QCD，并提出了Baryons的新模型。他研究了非（反）换向超空间中的非线性Sigma模型的新型非线性Sigma模型。
