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 提案旨在实现欧洲粒子物理战略中设定的目标，即充分利用高光度 LHC 的物理潜力。该实验旨在利用 LHC 中重口味（美丽和魅力）粒子的高生产率LHCb 升级 II 建立在 LHCb 实验现有基础设施的基础上，升级了所有子探测器系统和新元件，这些元件将提供解析来自不同粒子的能力。通过使用精确定时信息，同一束中的碰撞。数据将以比目前更高的速率记录，从而产生一个广泛而令人兴奋的物理计划，这是任何其他实验都无法比拟的。该提案适用于一个为期 3 年的研发项目在英国内部开发具体的战略技术，以实现 LHCb 升级 II 的物理目标。这将使我们能够与英国工业界建立联系，并通过准备 LHCb 升级 II 框架 TDR 以及子探测器特定的 TDR 继续领导国际合作。英国团体对解决顶点和跟踪带电强子方面的挑战特别感兴趣通过开发战略技术来识别和数据处理，并且该项目被相应地构建为工作包。我们计划在这个初始项目之后进行子探测器的原型设计和构建的进一步阶段，并最终进行实验和分析的操作data.这些后期阶段的资金请求当然将单独提出。
