Studies in Heavy Flavor Physics

罗切斯特大学的一个小组提出了一项建议，要求支持他们在康奈尔电子储存环（CESR）设施上继续开展CLEO合作研究，该小组计划改进B - sg中光子能谱的测量，研究排他性和包容性B- ulv衰变，研究轻子和半轻子粲衰变。这些活动将导致更好地了解Cabibbo-Kobayashi-Maskawa（CKM）矩阵元素|VUB|和|VCB|首先是直接的，然后是间接的，通过提供有助于解释B工厂、BaBar和贝儿的测量结果的信息。它还将导致更好的知识，|VCs|和|VCD|，允许精确测试CKM矩阵的么正性。

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.
