The Cincinnati group is expert in Flavor Physics and continues to make significant contributions to the physics of charm and heavy quarks. These contributions have come most recently through participation in the BaBar Experiment, whose active operations have ended, but whose data legacy is extensive and is being currently mined for important physics results. The Cincinnati group is now transitioning to the LHCb experiment at the CERN Large Hadron Collider, which is currently in an intense data-taking phase for 2012, and which will segue into an analysis and upgrade phase during the period 2013-2014. In the physics of BaBar, Cincinnati is focusing on a mixing analysis of neutral D decays, on a precision measurement of the mass difference between charged and neutral D mesons, and absolute mass measurements of charged and neutral D mesons. At LHCb the group will work on charm mixing and CP Violation, studies that can assess indirectly high mass scales and provide powerful constraints on models for new physics beyond the standard model. Among the processes of interest are three-body decays of neutral D mesons with Kshort mesons in the final state and amplitude analyses of four-body neutral D decays. Technically, the group intends to make contributions to the LHCb High Level Trigger with emphasis on increasing the efficiency of charm decays, and notably increasing the sensitivity to triggering on Kshort mesons. For the LHCb upgrades, the group will be working on tracking simulation, and in the domain of core computing, the group will contribute to the maintenance of the Conditions Database. The Cincinnati group has a strong record in education and outreach, and has had a very active QuarkNet Center since 2004, which offers local and regional high school teachers and students several opportunities. Among these are opportunities for teachers and students to participate directly in the research program; participation in QuarkNet International Masterclasses; and through their annual Teachers' Institute, the group has helped local high school teachers introduce particle physics and related topics in modern physics into their courses.

辛辛那提小组是味物理学方面的专家，并继续为粲夸克和重夸克物理学做出重大贡献。这些贡献是最近通过参与 BaBar 实验而做出的，该实验的活跃操作已经结束，但其数据遗产非常广泛，目前正在挖掘重要的物理结果。 辛辛那提小组目前正在转向 CERN 大型强子对撞机的 LHCb 实验，该实验目前正处于 2012 年的紧张数据采集阶段，并将在 2013 年至 2014 年期间进入分析和升级阶段。 在 BaBar 物理学中，辛辛那提专注于中性 D 衰变的混合分析、带电和中性 D 介子之间质量差的精确测量，以及带电和中性 D 介子的绝对质量测量。 在 LHCb，该小组将致力于魅力混合和 CP 破坏，这些研究可以间接评估高质量尺度，并为标准模型之外的新物理模型提供强大的约束。 感兴趣的过程包括终态 K 短介子的中性 D 介子的三体衰变以及四体中性 D 衰变的振幅分析。 从技术上讲，该小组打算为 LHCb 高电平触发做出贡献，重点是提高魅力衰变的效率，特别是提高 Kshort 介子触发的灵敏度。 对于LHCb的升级，该小组将致力于跟踪模拟，而在核心计算领域，该小组将致力于条件数据库的维护。辛辛那提集团在教育和推广方面拥有良好的记录，自 2004 年以来一直拥有非常活跃的 QuarkNet 中心，为当地和地区高中教师和学生提供了多种机会。 其中包括教师和学生直接参与研究项目的机会； 参加 QuarkNet 国际大师班；通过每年一度的教师学院，该小组帮助当地高中教师将粒子物理学和现代物理学的相关主题引入到他们的课程中。
