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探测器的第二次重大升级，LHCb升级II，将通过提供独特的探测能力，最大限度地发现高亮度LHC的潜力。这项实验旨在利用大型强子对撞机中重味(美丽和魅力)粒子的高产生率，通过环路过程实现对标准模型以外的物理学的精确搜索。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件进行了升级，这些新元件将提供通过使用精确计时信息来解决同一束不同碰撞中的粒子的能力。数据将以比目前可能的速度高得多的速度记录，这将导致一个广泛而令人兴奋的物理计划。该项目是英国LHCb升级II工作的三年前期建设阶段，2023年10月至9月。2026年，跟踪并在早期研发的基础上，完成和审查次级探测器技术设计报告。预计随后将是施工阶段，以及随后的安装、运营和物理开发。施工前和施工阶段的资金由英国皇家国际研究院基础设施基金拨款。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，同时也取得广泛的影响。
