用$B^0_s \rightarrow D_s^{\pm} K^{\mp} $衰变寻找新物理

Searching for New Physics with $B^0_s \rightarrow D_s^{\pm} K^{\mp} $ Decays

Robert Fleischer, Eleftheria Malami

摘要:

检验标准模型的特别有趣的过程是非轻子$B^0_s \rightarrow D_s^{\pm} K^{\mp}$跃迁。由于这些衰变是通过纯树图发生的,它们允许从理论上清晰地确定幺正三角形的角度$γ$。考虑到最近的LHCb结果,一个有趣的画面出现了,显示与标准模型的紧张关系。利用现有的实验数据,我们进行了理论分析,以阐明这些令人困惑的模式。这些谜题真的表明了新物理学的足迹吗?

英文摘要:

Particularly interesting processes to test the Standard Model are non-leptonic $B^0_s \rightarrow D_s^{\pm} K^{\mp}$ transitions. As these decays occur via pure tree diagrams, they allow a theoretically clean determination of the angle $γ$ of the unitarity triangle. Considering recent LHCb results, an intriguing picture arises, showing tension with the Standard Model. Utilising the available experimental data, we perform a theoretical analysis in order to shed more light on these puzzling patterns. Do these puzzles actually indicate footprints of New Physics?
