项目摘要

A part of research results of our project for three academic years in 1995-1997 are as follows :1.Dynamical Symmetry Breaking and Grand Unified Theories : K.Aoki developed a new renormalization group method for analyzing gauged NJL model and gave an approximation method going beyond the Higashijima-Miransky improved ladder approximation. Bando investigated the possibility of dynamical gauge bosons and its relevance to the Standard Model and GUT theories. Harada studied various problems in the light-cone quantization of field theories. H.Suzuki proposed a gauge-covariant formulation of chiral fermion on the lattice which uses the idea of covariant regularization in continuum theory. Kugo clarified the conditions under which the gauge-Higgs-Yukawa system becomes nontrivial, using the renormalization group equation. Nakano reviewed the dynamical supersymmetry breaking based on anomalous U (1) gauge symmetry. Suehiro quantized the extended Cherm-Simons theories in general dimensions. Sugamoto studied problems concerning B-meson decays, electroweak baryogenesis and neutron electric dipole moment.2.Duality and Non-Perturbative Dynamics in Supersymmetric Gauge Theories and String Theories : M.Kato proposed an ambitious theory which gives a non-perturbative definition of the string theory starting with non-commutative space-time. Kazama calculated for the first time the elastic scattering amplitude of quantized D-particles with a finite mass. Kunitomo constructed a topological field theory which describes the ground state of D-5 brane and considered the possibility of the second quantization of D-5 brane. Matsuo gave a simple derivation of the BPS condition for string junctions and examined the U-duality calculating the mass formula for the D-brane BPS states. Yahikozawa calculated systematically the effective action for the stringy vortices.

1995年至1997年，我们项目的研究成果的一部分如下：1。动力对称性和统一理论：K.Aoki开发了一种新的重新归一化组方法，用于分析测量的NJL模型，并提供了一种超越Higashijima-Miransky-Miransky的近似方法。 Bando研究了动力学玻色子的可能性及其与标准模型和肠道理论的相关性。原田研究了野外理论的轻锥量化问题。 H.Suzuki提出了在晶格上的手性武器的量规配方，该表格使用了连续理论中的协变正则化的概念。 Kugo阐明了使用重新归一化组方程，量规含量雄性系统变得不平凡的条件。 Nakano审查了基于异常U（1）量规对称性的动力超对称性破裂。 Suehiro在一般维度中量化了扩展的Cherm-Simons理论。 Sugamoto研究了有关B-梅森衰减，电动性重摩生成和中子电偶极矩时的问题。2。超对称规格理论的双重性和非扰动动力学：M.kato提出了一种雄心勃勃的理论，该理论具有对弦乐理论的非扰动定义，该理论始于非传授空间时间。卡萨马首次计算具有有限质量的量化D粒子的弹性散射幅度。 Kunitomo构建了一个拓扑场理论，该理论描述了D-5 Brane的基态，并考虑了D-5 Brane的第二次量化的可能性。 Matsuo给出了字符串连接的BPS条件的简单推导，并检查了D-Brane BPS状态的质量公式的U-二元性。 Yahikozawa系统地计算出丝状涡流的有效作用。
