LHCb Upgrade: Additional Equipment

LHCb是在欧洲核子研究中心的大型强子对撞机（LHC）上进行的粒子物理实验。它是该领域世界领先的物理实验，具有探索超越标准模型的物理的独特能力。LHCb的主要目标是通过对物质反物质不对称（CP违反）和含有美夸克和粲夸克的粒子的罕见衰变的精确测试，寻找超越标准模型的新物理学。由于其独特的设计和覆盖的角度区域更接近其他大型强子对撞机主要实验的光束，该实验在其他领域也有世界级的项目。现在有机会大幅增加LHCb项目的覆盖范围，并扩大其物理概况。英国小组提议领导升级VELO（顶点定位器），LHC中最精确的顶点探测器，以及LHCb独特的RICH（环成像切伦科夫）粒子识别（PID）系统。物理性能研究、计算、重建软件和触发算法开发以及参与新的闪烁光纤跟踪器的计划补充了这项工作。

LHCb is a particle physics experiment operating at the Large Hadron Collider (LHC) at CERN. It is the world's leading physics experiment in its field and has a unique capability to explore physics beyond the Standard Model. LHCb's main aim is to search for new physics beyond the Standard Model through precision tests of matter anti-matter asymmetries (CP violation) and rare decays of particles containing beauty and charm quarks. The experiment also has world-class programmes in other areas due to its unique design and coverage of an angular region closer to the beams that at the other main LHC experiments.The opportunity now exists to dramatically increase the reach of LHCb's programme and to widen its physics profile. The UK groups propose to lead the upgrade of the VELO (Vertex Locator), the most precise vertex detector at the LHC, and LHCb's unique RICH (Ring Imaging Cherenkov) particle identification (PID) system. A programme of physics performance studies, computing, reconstruction software and trigger algorithm development, and involvement in a new scintillating fibre tracker complements this work.
