项目摘要

The research plan presented in 1993 states that we obtain an effective chirally invariant lagrangian which is applicable at low energies. This lagrangian contains dynamics of rho, omega, phi, A,K,pi, eta. This work was published by my student Hayakawa and my self in the Progress for Theoretical Physics. We have discussed a difficult problem of how to break SU (3) symmetry in detail.Hayakawa and I also investigated how one may experimentally test the validity of P,T,CPT symmetry. This is particularly relevant as the phifactory is being constructed in Italy. This work was published in The Physical Review.Upon my suggestion to work on the heavy quark symmetry, Kitazawa and Kurimoto investigated the connection between chiral symmetry and heavy quark symmetry. This work, " Heavy Meson Effective Theory with 1/M Correction" was published in Physics Letters.The 1994 research plan was to investigate the connection between the Kobayasi-Maskawa matrix and the quark mass matrix. Some progress is made in this direction.1995 research plan called for investigation of correction to muon g-2 coming from the light-by-light scattering. In particular, the hadronic contribution to the light-by-light scattering is hyghly nontrivial. We have used hidden local symmetry approach to analyze this problem. The result has been published in The Physical Review Letters.

1993年提出的研究计划指出，我们得到了一个有效的手征不变的拉格朗日量，这是适用于低能量。这个拉格朗日量包含了ρ，ω，φ，A，K，pi，eta的动力学。这项工作是由我的学生Hayakawa和我本人在《理论物理进展》上发表的。我们详细讨论了如何破缺SU（3）对称性这一难题，Hayakawa和我还研究了如何用实验检验P，T，CPT对称性的有效性。由于phifactory正在意大利建造，这一点尤其重要。这项工作发表在《物理评论》上。在我的建议下，北泽和栗本研究了手征对称性和重夸克对称性之间的联系。这项工作，“重介子有效理论与1/M修正”发表在物理快报。1994年的研究计划是调查之间的连接小林-Maskawa矩阵和夸克质量矩阵。1995年的研究计划要求研究μ介子g-2的光-光散射修正。特别地，强子对光-光散射的贡献是高度非平凡的。我们使用隐藏的局部对称性方法来分析这个问题。该研究结果发表在《物理评论快报》上。
