论文摘要
non-leptonic $ b^0_s \ rightarrow d_s^{\ pm} k^{\ mp} $ transitions是测试标准模型的特别有趣的过程。由于这些衰变通过纯树图发生，因此它们可以在理论上清洁单位三角形的角度$γ$的确定。考虑到最近的LHCB结果，出现了一个有趣的图片，显示了标准模型的张力。提取基础$ \ bar {b}^0_s \ rightArrow d_s^{\ pm} k^{\ mp} $模式的分支比率，并将它们与半蛋白质的$ b _ {（s）} $衰减中的信息结合在一起，我们获得了另一个令人困惑的情况，根据类似的差异。这些模式可能是新物理学的足迹。我们提出了一种与模型无关的策略，以包括这种新物理效应并将其应用于数据。有趣的是，中等规模的新贡献可以容纳数据。这种形式主义为未来的高精度B物理时代的新违规来源提供了令人兴奋的调查。
Non-leptonic $B^0_s \rightarrow D_s^{\pm} K^{\mp}$ transitions are particularly interesting processes to test the Standard Model. 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. Extracting the branching ratios of the underlying $\bar{B}^0_s \rightarrow D_s^{\pm} K^{\mp}$ modes and combining them with information from semileptonic $B_{(s)}$ decays, we arrive at another puzzling situation, in accordance with similar decays. These patterns could be footprints of New Physics. We present a model-independent strategy to include such New-Physics effects and apply it to the data. Interestingly, new contributions of moderate size could accommodate the data. This formalism offers an exciting probe for new sources of CP violation at the future high-precision B physics era.
