K PHYSICS AT KEK WITH THE PRESENT 12-GEV AND FUTURE 50-GEV PS

摘要

The current status of the two K-decay experiments, which are now underway with the 12-GeV proton synchrotron (PS) at KEK, is reported. One is to detect a rare decay mode K-L --> pi(+)pi(-)e(+)e(-), and the other to search for the T-violation in the K+ --> pi(0) mu(+)nu decay. Some commence are also given on possible K-decay experiments with a high-intensity 50-GeV PS, which is proposed to build in the near future at KEK. [References: 28]
