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 一直在研究在三个空间维度上构建 2 重超对称模型，这项研究是他之前关于非线性超对称性工作的延伸，他与合作研究人员在研究某些微扰序列的渐近行为时发现了这一点。量子力学模型并创造了术语“N重超对称性”三维，因为所述扩展的超对称代数引入了一组复杂的非线性微分方程，这是相当难以解决的，H. Aoyama在过去几年中一直致力于解决这个问题，并且接近完成完整的构造和分类。三维模型的应用非常广泛，更不用说其崇高的理论地位了。松田一直在研究额外的维度，他假设宇宙学常数会出现。他还计算了卡西米尔能量作为模参数的函数，并使用从 WMAP 获得的宇宙常数值将额外维度的大小评估为亚毫米量级。在超维空间是二维环面的情况下，他还考虑了超维空间预测的微型黑洞的产生，并研究了广义不确定性原理，这项研究将有助于更好地评估超维空间的产生截面。 K. Yamamoto 致力于超对称电弱模型的扩展，包括轻子数生成、多维标量场运动生成重子数及其对暗物质运动的贡献。他在势平坦空间上研究了多维标量场，发现它可以有效地产生非对称粒子数，从而阐明了轻子数产生与中微子质量之间的关系。
