LHCb 实验旨在利用 LHC 产生的美丽强子的巨大通量来对 CP 破坏进行高精度测量并寻找新物理。 LHCb探测器是一款单臂光谱仪，具有出色的跟踪和粒子识别能力。运行情况以及从 2010 年和 2011 年收集的数据中获得的结果表明，探测器非常稳健且功能良好。在接下来的几年中，LHCb 将测量重度风味衰减中大量有趣的通道。然而，如果不改进检测器，每年 1 fb−1 数据的限制就无法克服。升级后的光谱仪具有 40MHz 读数和更加灵活的基于软件的触发系统，将提高数据速率和效率，特别是在强子通道中，从而扩大我们的物理范围，超越重口味的范围。在这里，回顾了不同探测器正在研究的不同可能性以及正在进行的研发活动。
The LHCb experiment is designed to perform high-precision measurements of CP violation and search for New Physics using the enormous flux of beauty and charmed hadrons produced at the LHC. The LHCb detector is a single-arm spectrometer with excellent tracking and particle identification capabilities. The operation and the results obtained from the data collected in 2010 and 2011 demonstrate that the detector is robust and functioning very well. In the next years, LHCb will measure a large number of interesting channels in heavy flavor decays. However, the limit of 1 fb−1 of data per year cannot be overcome without improving the detector. An upgraded spectrometer with a 40MHz readout and a much more flexible software-based triggering system will increase the data rate as well as the efficiency specially in the hadronic channels, widening our physics scope beyond that of heavy flavor. Here, the different possibilities under study for the different detectors are reviewed as well as the ongoing R&D activities.
