论文摘要

我们在$ b^{0,+} \至k^{*0,+}μ^+μ^ - $ $衰减的标准模型中进行分析,鉴于LHCB实验的最新测量值,这表明新数据增强了对它们中可观的耐药贡献和相关性的需求。然后,我们通过标准模型有效理论将分析扩展到新物理学,并进行可用的$ b \ s \ ell^+ \ ell^ - $数据的最先进的拟合度,包括可能的HADRONIC贡献。我们发现,完全左撇子的操作员是最简单的情况,其意义近6σ$。

We perform an analysis within the Standard Model of $B^{0,+} \to K^{*0,+} μ^+ μ^-$ decays in light of the recent measurements from the LHCb experiment, showing that new data strengthen the need for sizable hadronic contributions and correlations among them. We then extend our analysis to New Physics via the Standard Model Effective Theory, and carry out a state-of-the-art fit of available $b \to s \ell^+ \ell^-$ data, including possible hadronic contributions. We find the case of a fully left-handed operator standing out as the simplest scenario with a significance of almost $6σ$.
