Studies in Heavy Flavor Physics

来自罗彻斯特大学的一个小组的提案要求支持他们在康奈尔电子存储环（CESR）设施的CLEO合作中继续研究。该小组计划改进b- sg中光子能谱的测量，研究b- ulv的独占性和包容性衰变，并研究轻子和半轻子粲衰变。这些活动将通过提供有助于解释b工厂、BaBar和Belle测量结果的信息，首先直接地，然后间接地提高对Cabibbo-Kobayashi-Maskawa （CKM）矩阵元素|Vub|和|Vcb|的认识。它还将提高| vc |和|Vcd|的知识，从而可以精确地测试CKM矩阵的统一性。

This proposal from a University of Rochester group requests support to continue their studies within the CLEO collaboration working at the Cornell Electron Storage Rings (CESR) facility.The group plans to improve the measurements of the photon energy spectrum in b - sg, to study the exclusive and inclusive b- ulv decays and to study leptonic and semi-leptonic charm decays. These activities will lead to improved knowledge of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements |Vub| and |Vcb| first directly and later indirectly by supplying information that aids in the interpretation of measurements at the B-factories, BaBar and Belle. It will also lead to improved knowledge of |Vcs| and |Vcd|, allowing precise tests of the unitarity of the CKM matrix.
