KEK Accelerator Facility

KEK 加速器设施

The KEK accelerator facility was established in 1997 in a reorganization of the Institute of Nuclear Study, University of Tokyo. The nature of the equipment may be seen at their images site. The location is on the south coast of Japan.

KEK加速器设施于1997年在东京大学核研究室重组中建立。设备的性质可通过其图片网站查看。该地点位于日本的南海岸。

The B-Factory at the KEK Accelerator Facility

B-工厂位于KEK加速器设施中

The B-factory accelerator at KEK (KEKB) collides 8 billion electron volts (8 GeV) electrons with 3.5 GeV positrons to produce large number of B mesons, tau particles, and charmed particles. "Investigations of large numbers of B mesons, tau particles and charm mesons, which are produced inside an experiment at the KEKB electron-positron accelerator collider, reveal violations of the symmetry between particles and anti-particles. These are rare phenomena that occurred at an early stage of the universe, and may reveal the nature of unknown particles and new interactions. In addition, these breakdowns of symmetry may lead us to new laws of physics and an understanding of why anti-matter has disappeared from the universe."KEK)

KEK的B工厂加速器（KEKB）让8 GeV电子与3.5 GeV正电子对撞，产生大量B介子、陶轻子和含粲粒子。对KEKB对撞实验产生的大量B介子、陶轻子和粲介子的研究，揭示了粒子与反粒子之间的对称性破坏。这些在宇宙早期曾发生的罕见现象，可能帮助我们理解未知粒子和新的相互作用；相关对称性破坏也可能引出新的物理规律，并帮助解释宇宙中的反物质为何消失。
