摘要/Abstract

摘要： Belle II／超级KEKB实验是一个在Y（4S）共振态能量点运行产生B介子对的正负电子对撞机.作为Belle／KEKB实验的升级，它将从2018年开始以大约40倍的亮度取数，目标是收集50 ab-1的正负电子对撞数据.现在子探测器系统的升级正在KEK进行.物理项目涉及范围很宽，包括寻找直接CP破坏、轻子味破缺、暗物质.本文回顾当前Belle II和超级KEKB升级状况并介绍该设施带来的物理机遇.

关键词: Belle II, 超级KEKB, 正负电子对撞机, 新物理

Abstract: The Belle II/SuperKEKB experiment is an e+e- collider running at the Υ(4S) resonance energy to produce B meson pairs. As an upgrade of the Belle/KEKB experiment, it will start physics data taking from 2018 and with ~40 times luminosity. Its goal is to accumulate 50 ab-1 of e+e- collision data. Now the upgrade of the sub-detector systems is on-going in KEK. The physics program has a wide range of areas, including searches for direct CP violation (CPV), lepton flavour violation and dark matter. The current upgrade status of Belle II and SuperKEKB is reviewed and some physics opportunities at this facility are introduced.

Key words: Belle II, SuperKEKB, e+e- collider, New Physics
