The Michigan State Group plans to continue its research on top quark physics using the Collider Detector at Fermilab (CDF) and use this expertise from CDF to contribute to the ATLAS experiment at the Large Hadron Collider (LHC) located at CERN in Geneva, Switzerland. The group is currently working on measuring the charge of the top quark, which the SM predicts to be +2/3 but there are non-SM theories that allow for an exotic top quark with charge -4/3. Additionally the group is working with matrix element techniques that can be applied to the search for a non-Standard Model W boson which might decay into a single top quark plus a bottom quark. Ultimately it is planned to use this technique to search for Higgs Bosons in the WH Channel at the LHC. Over the next three years the group will gradually transition to the ATLAS experiment. As a fundamental feature of the research effort, the group is dedicated to encouraging minorities, especially women, to become interested in science and pursue careers in physics.

密歇根州立集团计划利用费米实验室 (CDF) 的对撞机探测器继续进行顶夸克物理研究，并利用 CDF 的专业知识为位于瑞士日内瓦欧洲核子研究中心 (CERN) 大型强子对撞机 (LHC) 的 ATLAS 实验做出贡献。该小组目前正在测量顶夸克的电荷，SM 预测其电荷为 +2/3，但非 SM 理论允许奇异的顶夸克电荷为 -4/3。 此外，该小组正在研究矩阵元技术，该技术可用于搜索非标准模型 W 玻色子，该玻色子可能会衰变成单个顶夸克和底夸克。 最终计划使用这项技术在大型强子对撞机的WH通道中寻找希格斯玻色子。 在接下来的三年里，该小组将逐步过渡到 ATLAS 实验。 作为研究工作的一个基本特征，该小组致力于鼓励少数族裔，特别是女性，对科学产生兴趣并从事物理学事业。
