The LHCb Upgrade II proposal addresses the goal set out in the European Strategy for Particle Physics of exploiting fully the physics potential of the High Luminosity LHC.The experiment is designed to exploit the high production rate of heavy flavoured (beauty and charm) particles in LHC collisions, enabling precision searches for physics beyond the Standard Model through loop processes.LHCb Upgrade II builds on the existing infrastructure of the LHCb experiment, with upgrades to all subdetector systems and new elements that will provide capability to resolve particles from different collisions in the same bunch crossing through the use of precision timing information.Data will be recorded at much higher rates than currently possible, leading to a broad and exciting physics programme, unmatched by any other experiment.This proposal is for a 3 year R&D project within the UK to develop specific, strategic technologies that will enable the physics goals of LHCb Upgrade II to be achieved. This will allow us to develop links with UK industry and continue to lead the international collaboration through preparation of the LHCb Upgrade II framework TDR as well as subdetector-specific TDRs.The UK groups have particular interests in addressing challenges in vertexing and tracking, charged hadron identification and data processing by developing strategic technologies, and the project is structured into workpackages accordingly.We plan that this initial project be followed by further stages for prototyping and construction of the subdetectors, and eventually to operation of the experiment and analysis of the data.Requests for funding of these later stages will of course be made separately.

LHCb升级II计划解决了欧洲粒子物理战略中提出的目标，即充分开发高亮度LHC的物理潜力。该实验旨在利用LHC碰撞中重味(美丽和魅力)粒子的高产生率，通过环路过程精确搜索标准模型以外的物理。LHCb升级II建立在LHCb实验的现有基础设施上，对所有子探测器系统和新元素进行升级，这些新元素将通过使用精确的计时信息来提供在同一束中解析来自不同碰撞的粒子的能力。数据将以比目前可能的更高的速度记录，从而产生一个广泛而令人兴奋的物理计划，这项提议是为了在英国进行一个为期3年的研发项目，以开发特定的、战略性的技术，使LHCB升级II的物理目标得以实现。这将使我们能够与英国工业界发展联系，并通过准备LHCb升级II框架TDR以及特定于子探测器的TDR继续领导国际合作。英国小组对通过开发战略技术来解决顶点和跟踪、带电强子识别和数据处理方面的挑战特别感兴趣，并相应地将该项目组织成工作包。我们计划在这一初步项目之后进行进一步的阶段，用于原型和子探测器的建造，并最终运行实验和数据分析。这些后续阶段的资金申请当然将另行提出。
