Studies in Heavy Flavor Physics

该提案旨在支持罗切斯特大学的一个由PI、两名博士后助理和三名学生组成的小组进行“CLEO-c”实验。这个实验在产生高质量的粲粒子衰变数据方面具有巨大的潜力，远远超过以往的所有数据。其中一些结果，例如那些与“晶格QCD”比较有关的结果，将在计算强相互作用强度方面具有理论重要性；绝对分支分数的测量对于理解较重夸克的衰变非常重要，并有助于解释“B工厂”BaBar（美国）和Belle（日本）的测量结果；该实验将提高对“CKM矩阵元素”的认识，使精确测试描述弱相互作用的CKM矩阵的统一性成为可能。

This proposal is to support a group from the University of Rochester consisting of the PI, two postdoctoral associates, and three students, in their work on the "CLEO-c" experiment. This experiment has significant potential for producing high quality data on charm particle decays that far exceed all previous data. Some of these results, for example those relating to "lattice QCD" comparisons, will be of theoretical importance in calculating strong interaction strengths; the measurements of absolute branching fractions will be important for understanding decays of heavier quarks and aid in the interpretation of measurements at the"B factories" BaBar (US) and Belle (Japan); and the experiment will improved knowledge of the "CKM matrix elements" which will make possible precise tests of the unitarity of the CKM matrix describing weak interactions. .
