| Research Abstract |
The aim of this research was a detailed study of physics scenario for experiment using the next generation electron-positron collider JLC (Japan Linear Collider) and R & D of its detector.
1. By upgrading simulation program for physics and detector, and taking into account the recent information from Tevatron on top quark and from LEP-2 experiments, we studied all the possible expected physics channels at JLC Phase-1 (center-of-mass energy=300-500GeV) and at JLC Phase-2 (1-1.5TeV). In particular, we made a detailed study of Higgs and SUSY particles, which are now considered to exist in relatively lower energy region, and showed that both can surely be observed in JLC Phase-1 experiment.
2. By considering interface between the detector and accelerator near the collision point, we performed detector R & D in parallel with accelerator R & D.We made not only the study using the detector simulation program, but also detector R & D by constructing some prototype detector elements. As a result, it was shown that a detector of sufficiently high performance for JLC experiment can be built with the present detector technology.
3. We studied physics and experimental technology for electron-positron collider experiment with polarized beams. We also studied about a possibility of converting JLC into photon-photon collider.
As a result of this study, we obtained stronger motivation for the importance and urgency of JLC Phase-1, and we paved a way for optimization and detailed design of the detector.
