Super KEKB和Belle II:KEK Super B工厂的状态

Super KEKB and Belle II: Status of the KEK Super B Factory

Zdenek Dolezal

摘要:

KEKB正负电子对撞机上的Belle探测器在其十年的运行中收集了大约8亿次Upperdance(4S)事件。KEKB小组已经提出了超级KEKB,这是KEKB的升级,在三年的关闭期间将光度提高两个数量级,最终目标是8 E35/cm^2/s的光度。为了利用增加的亮度,已经提出了对Belle探测器的升级。一个新的国际合作Belle-II正在形成,欧洲研究所的参与更广泛。Super-KEKB和Belle-II于2008年初正式列入KEK五年路线图。本文介绍了加速器升级的物理动机、基本方法以及探测器的关键改进。更多的细节是关于DEPFET像素探测器,将完全建立在欧洲。

英文摘要:

The Belle detector at the KEKB electron-positron collider has collected approximately 800 million Upsilon(4S) events in its decade of operation. The KEKB group has proposed Super-KEKB, an upgrade of KEKB to increase the luminosity by two orders of magnitude during a three-year shutdown, with an ultimate goal of 8E35/cm^2/s luminosity. To exploit the increased luminosity, an upgrade of the Belle detector has been proposed. A new international collaboration Belle-II, is being formed, with a broader participation of European institutes. Super-KEKB and Belle-II were officially placed on the KEK 5-year Roadmap in early 2008. The paper presents physics motivation, basic methods of the accelerator upgrade, as well as key improvements of the detector. More details are given on the DEPFET pixel detector that will be completely built in Europe.
