从τ衰变中测定|Vus|

Determination of |Vus| from tau Decays

Ian M. Nugent

摘要:

第一代和第二代夸克之间的弱相互作用,Cabibbo-Kobayashi-Maskawa矩阵(CKM)元素|Vus|,可以用强子τ衰变来探测。本文介绍了BELLE和BABAR最近对强子τ衰变的测量以及τ衰变中确定|Vus|的改进。

英文摘要:

The weak interaction between the first and second generation of quarks, the Cabibbo-Kobayashi-Maskawa matrix (CKM) element |Vus|, can be probed using hadronic tau decays. In this paper, we present the recent measurements of hadronic tau decays from BELLE and BABAR and the improvements in the determination of |Vus| from tau decays.
