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.

该研究计划涉及对大型强子对撞机（LHC）的质子 - 普罗顿碰撞的研究。该研究的主要目的是在所谓的标准模型中搜索并检查新粒子和自然定律的可能证据，这代表了我们当前对物质基本成分以及控制其相互作用的法律的理解。 据信标准模型是不完整的，因为它未能说明一些重要的发现和问题，例如宇宙中抗物质的物质明显失衡以及从天文学观察中推断出的暗物质的有力证据。该项目将涉及对物质颗粒行为差异的精确测量，与它们的反物质对应物相比，其结果可能揭示了有关自然界观察到的物质 - 抗抗剂不平衡的起源的信息，这对于理解宇宙如何演变为其当前状态至关重要。 除了这些基本的研究目标外，该研究计划的资金还可以培训下一代的科学家和工程师，包括本科生，博士学位。研究生，博士后研究人员和工程师在粒子物理研究领域工作的研究者，具有最先进的数据分析和计算技术，电子仪器以及粒子和辐射检测技术。这项研究是用LHC Collider的LHCB粒子检测器在Cern Laboratoration的LHCB粒子探测器进行的。 该研究的具体重点是研究涉及包含底部夸克或魅力夸克的颗粒的反应。这些研究允许对标准模型进行精确测试，这可能揭示了与其预测的偏差。 这些发现以及能源前沿实验的预期结果可以帮助发现自然法则，并指向超出标准模型以外的新物理结构的道路。 该研究计划还涉及LHCB检测器的升级，这是LHC撞机较高光度的操作所必需的。 探测器升级工作集中在设计和记录LHCB磁铁上游的硅条形跟踪系统中的电子仪器的设计上。
