Charm Physics at CLEO-c, Beauty Physics at LHCb

锡拉丘兹大学正致力于研究碰撞束流加速器中产生的“魅力”和“美丽”粒子。科学驱动因素包括对b和c夸克弱衰变的研究，以及重夸克衰变中新的“超越标准模型”状态的可能参与（通过虚拟循环）。事实上，测量重夸克的衰变可能是识别“新物理学”存在的重要途径。该小组采用了双管齐下的方法：在CLEO-c实验中积极分析魅力状态的数据，并努力使LHCb实验准备好获取数据，以研究美貌物理。CLEO-c的职责包括维护在锡拉丘兹为实验建造的环形成像切伦科夫探测器（RICH）。在该小组领导的几项数据分析中，测量了D+介子B（D+ mu+中微子）和伪标量衰变常数f（D+）的两体轻子衰变的分支比，以及Y（1D）和Dsj（2463）态的首次观测。该小组现在积极参与LHCb探测器的几个方面，包括顶点探测器、在线事件选择监测（称为触发）、全局对齐和RICH探测器。该计划的更广泛影响潜力是广泛的，包括在RICH光子探测器方面取得的重大进展的技术转让，以及通过广泛使用的“询问粒子物理学家”等项目进行的教育和推广，以及通过本科生的研究机会。

Syracuse University is focusing its research efforts on the study of Charm and Beauty particles produced in colliding beam accelerators. The science drivers include studies of the weak decays of b and c quarks, and the possible participation (through virtual loops) of new "beyond the Standard model" states in heavy quark decay. In fact, measurements of the decays of heavy quarks may be an important way to identify the presence of "new physics". The group uses a two-pronged approach: working on the CLEO-c experiment actively analyzing data on charm states, and working on getting the LHCb experiment ready to take data, to study beauty physics. CLEO-c responsibilities include maintaining the Ring Imaging Cherenkov Detector (RICH) constructed at Syracuse for the experiment. Among the several data analyses led by the group are measurement of the branching ratio for the two-body leptonic decay of the D+ meson B(D+ mu+ neutrino) and the pseudoscalar decay constant f(D+), and first observation of Y(1D) and Dsj(2463) states. The group is now actively engaged in several aspects of the LHCb detector, including the vertex detector, monitoring of the online event selection (called triggering), global alignment and the RICH detector.Broader Impacts potential of the program is extensive including technology transfer of significant advances made in RICH photon detectors and education and outreach through programs such as the "Ask a Particle Physicist" that is in wide use, and through research opportunities for undergraduates.
