The second major upgrade of the LHCb detector, LHCb Upgrade II, will maximise the discovery potential of the High Luminosity LHC by providing unique detection capability. 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. This project is a three-year preconstruction phase of UK work on LHCb Upgrade II, Oct. 2023-Sep. 2026, following and building on earlier R&D through to the completion and review of subdetector technical design reports. It is anticipated to be followed by a construction phase, and subsequent installation, operation and physics exploitation. Funding for preconstructcion and construction phases has been allocated by a UKRI Infrastructure Fund award. UK effort is focussed on specific, strategic technologies that will enable the physics goals of LHCb Upgrade II to be achieved while also achieving broad impact.

LHCB检测器LHCB升级II的第二大升级将通过提供独特的检测能力来最大化高光度LHC的发现潜力。该实验旨在利用LHC碰撞中的重风味（美和魅力）颗粒的高生产率，从而可以通过环路工艺对标准模型以外的物理进行精确搜索。 LHCB升级II建立在LHCB实验的现有基础架构的基础上，并对所有子检测器系统和新元素进行了升级，这些元素将通过使用精密时序信息来解决相同群体中不同碰撞中的粒子的能力。数据的记录将比目前的速度高得多，从而导致广泛而令人兴奋的物理计划。该项目是2023年10月9日在LHCB升级II上的英国工作的三年前阶段。 2026年，遵循并在早期的研发上进行建设，以完成子检测器技术设计报告的完成和审查。预计之后将是施工阶段，并随后安装，操作和物理剥削。乌克里基础设施基金奖已分配了预建和建筑阶段的资金。英国的努力集中在特定的战略技术上，这些技术将使LHCB升级II的物理目标得以实现，同时也实现广泛的影响。
