The origin of elementary particle interaction

1)CP破坏的起源虽然在K衰变中观察到的CP破坏仅为0.2%，但KM模型预测在B衰变中几乎100%的CP破坏效应。为了理解CP破坏的起源，发现这种大的CP破坏是至关重要的。为了实现这一目标，必须创造大量的B介子，并必须研究衰变模式。目前，B工厂正在KEK和SLAC建设。两个实验室都在用最高水平的技术和物理相互竞争。作为日本高能社区的一员，我们希望看到KEK首先发现CP违反。为了实现这一目标，我们在KEK成立了一个研究小组来支持这一活动。夸克质量的起源A）在超对称大统一理论的框架内，研究了Georgi-Jarlskog质量矩阵。研究结果表明，G-J矩阵不能充分解释KM矩阵和夸克质量谱的值。B）NNI形式一般夸克矩阵有36个参数。结果表明，当它们变换为NNI形式时，一般质量矩阵可以写成12个参数。其中，6可以用6个夸克质量固定。我们已经成功地使用KM矩阵固定了4个其他参数。

1) The origin of CP violationWhile observed CP violation in K decay is only 0.2%, the KM model predicts nearly 100% CP violating effects in B decays. To understand the origin of CP violation it is crucial to discover this large CP violation. To achieve this goal, large number of B mesons must be created and the decay modes must be studied. At present B factory is being constructed at KEK and at SLAC.Both laboratories are competing against each other with the top level technology and physics. As a member of the Japanese high energy community we hope to see KEK discover CP violation first. To achieve this goal, we have initiated a study group to support this activity at KEK.The origin of quark massesA) Within the framework of SUSY GUT,Georgi-Jarlskog mass matrix was studied. The result of this study was that G-J matrix does not adequately explain the values of the KM matrix and the quark mass spectrum. How to get phases in to the mass matrix at the GUT scale is an important topic of the future study.B) The NNI formGeneral quark matrices have 36 parameters. It has been shown that when they are transformed to the NNI form, a general mass matrices can be written in terms of 12 parameters. Out of these, 6 can be fixed with 6 quark masses. We have succeeded in fixing 4 other parameters using the KM matrix.
