从树能级衰变测量$γ$

Measurements of $γ$ from tree-level decays

A. Bertolin

摘要:

本文介绍了用LHCb方法精确测定树能级衰变的CKM角$γ$。LHCb最多可提供16个独立的测定,使用各种美丽和魅力介子衰变模式。并不是所有的人都对$γ$有相同的敏感性。通过结合所有可用的结果来达到最佳的准确性。这些程序审查了合并中使用的一些独立测定结果,并提供了截至2018年夏季的最新合并结果。

英文摘要:

The LHCb approach for a precise determination of the CKM angle $γ$ from tree--level decays is presented. Up to 16 independent determinations, using a variety of beauty and charm mesons decay modes, are available at LHCb. Not all of them have the same sensitivity to $γ$. The best accuracy is reached by combining all of the available results. These proceedings review some of the independent determinations used in the combination and present the latest combined result available, as of Summer 2018.
