Experimental Study of Heavy Flavor and CP Violation with the LHCb Experiment at the CERN LHC Collider

这项研究计划包括在大型强子对撞机（LHC）上进行质子-质子碰撞的研究。这项研究的一个主要目标是寻找和检验超越所谓标准模型所描述的新粒子和自然定律的可能证据，标准模型代表了我们目前对物质基本成分和控制它们相互作用的定律的理解。标准模型被认为是不完整的，因为它不能解释一些重要的发现和问题，比如宇宙中物质相对于反物质的明显不平衡，以及从天文观测中推断出的暗物质存在的有力证据。该项目将包括对物质粒子与反物质粒子的行为差异进行精确测量，其结果可能会揭示自然界中观测到的物质-反物质不平衡的起源信息，这对于理解宇宙是如何演变到现在的状态至关重要。除了这些基础研究目标之外，本研究项目的资金还用于培养包括本科生、博士在内的各级科学家和工程师的下一代。研究生、博士后研究人员和工程师在粒子物理研究的前沿工作，采用最先进的数据分析和计算技术、电子仪器、粒子和辐射探测技术。本研究是在欧洲核子研究中心实验室的大型强子对撞机上使用LHCb粒子探测器进行的。研究的重点是研究含有底夸克或粲夸克的粒子的反应。这些研究允许对标准模型进行精确的测试，这可能会揭示其预测的可能偏差。这些发现，加上能量前沿实验的预期结果，可能有助于揭示新的自然定律，并为超越标准模型的新物理结构指明道路。该研究项目还包括LHCb探测器的升级，这是LHC对撞机在更高光度下运行所必需的。探测器升级工作的重点是电子仪器的设计，用于从位于LHCb磁体上游的硅条跟踪系统中提取和记录电信号。

This research program involves a study of proton-proton collisions at the Large Hadron Collider (LHC). A major goal of the study is to search for and examine possible evidences for new particles and laws of nature beyond those described in the so-called Standard Model, which represents our current understanding of the fundamental constituents of matter and the laws that govern their interactions. The Standard Model is believed to be incomplete, as it fails to account for some important findings and questions, such as the apparent imbalance of matter with respect to antimatter in the universe and strong evidence for dark matter, inferred from astronomical observations. This project will involve performing precise measurements of differences in behavior of matter particles compared with their antimatter counterparts, the results of which may reveal information on the origin of the observed matter-antimatter imbalance in nature, which is crucial to understanding how the universe evolved to its current state. In addition to these fundamental research goals, the funding for this research program enables the training of the next generations of scientists and engineers at all levels, including undergraduates, PhD. graduate students, postdoctoral researchers and engineers working at the frontier of particle physics research with the state of the art data analysis and computing techniques, electronics instrumentations and particle and radiation detection techniques.This research is carried out with the LHCb particle detector at the LHC collider at the CERN laboratory. The specific focus of the research is on studies of reactions involving particles that contain the bottom quark or the charm quark. These studies allow for precise tests of the Standard Model, which may reveal possible deviations from its predictions. The findings, together with expected results from experiments at the energy frontier, could help uncover new laws of nature and point the way to the structure of new physics beyond the Standard Model. The research program also involves the upgrade of the LHCb detector, which is required for operations at higher luminosity of the LHC collider. The detector upgrade effort is focused on the design of electronics instrumentation for extracting and recording electrical signals from a silicon strip tracking system located just upstream of the LHCb magnet.
