项目摘要

H. Aoyama has been investigating construction of 2-fold supersymmetric model in three spatial dimensions. This investigation is an extention of his previous work on nonlinear supersymmetry, which he, with co-investigators, discovered while examining asymptotic behavior of the perturbative series in some quantum mechanical models and coined the term "N-fold supersymmetry". Much is known about the original one-dimensiocal case, less so in two-dimensions, and none whatsoever in three-dimension, since the said extended supersymmetry algebra induces set of complex nonlinear differential equations, which were quite difficult to solve. H. Aoyama has been working on this problem for the last few years and is close to completion of the complete construction and classification of the three dimensional models, which would have a wide varietry of applications, not to mention its noble theoretical status.S. Matsuda has been looking into the extra dimentsions. He has hyposized that the consmological … More constant comes from the Casimir energy of the extra dimensions and evaluated the size of the extra dimensions to be of order of sub-millimeter using the value of the cosmological constant obtained from WMAP. He has alos calculated the Casimir enery as a funcion of the moduli parameters in case the extra-dimensional space is atwo-dimensional torus. He also considered mini-blackhole creation predicted by extra-dimensional space and investigated a generalized uncertainty principle. This research will lead to better evaluation of the creation cross-secton of the mini-blackholes.K. Yamamoto has worked on extensions of the supersymmetric electroweak models, including lepton number generation, baryon number generation by motion of multi-dimensional scalar field, and its contribution to dark matter. In particular, he has studied motion of the multi-dimensional scalar field on the flat-space of the potential and found that it generates non-symmetric particle numbers effectively. This way, he has clarified relation between leption number generation and neutrino masses Less

H. Aoyama一直在研究三个空间维度的2倍超对称模型的构建。这项投资是他以前关于非线性超对称性的工作的极端，他在某些量子机械模型中研究了扰动序列的不对称行为时发现了这一投资，并创造了术语“ n折叠超对称性”。对于原始的一二维核病例，在二维中较少了解，而在三维中却一无所知，因为所述扩展的超对称代数影响了一组复杂的非线性微分方程组，这很难求解。 H. Aoyama在过去的几年中一直在研究这个问题，并且接近完成三维模型的完整构造和分类，这些模型将具有广泛的应用程序变化，更不用说其崇高的理论状态了。 Matsuda一直在研究额外的尺寸。他降低了尚科学……更常数来自额外维度的Casimir能量，并使用从WMAP获得的宇宙常数值评估了额外尺寸的大小为亚毫米计的顺序。他的ALO将Casimir能量计算为模量参数的功能，以防超二维空间是差异的圆环。他还考虑了超维空间预测的迷你黑洞创建，并研究了普遍的不确定性原则。这项研究将导致更好地评估Mini-Blackholes.k的创建横形。 Yamamoto从事超对称电子模型的扩展，包括Lepton数量的产生，多维标量场运动的Baryon数量生成及其对暗物质的贡献。特别是，他研究了电势的平坦空间上多维标量场的运动，并发现它有效地产生了非对称粒子数。这样，他阐明了瘦素数量产生与神经元之间的关系较少
