融入还是孤立?$b\to s \ell^+\ell^-$中的拉取与残留响应

Fitting in or odd one out? Pulls vs residual responses in $b\to s \ell^+\ell^-$

Bernat Capdevila, Ursula Laa, German Valencia

摘要:

LHCb和Belle II合作最近报道了具有潜在夸克跃迁$b\to s \ell^+\ell^-$的过程的新结果。在本文中,我们将展示如何使用我们最近的论文arXiv:1811.10793中介绍的工具来理解一些新测量的主要含义,而无需重新进行全局拟合。我们发现,新结果的主要影响,由于$R_K^{[1.1,6]}$从LHCb,是减少了$C_{10μ}^{NP}$的不确定性。我们验证了这一结论,提出了一个新的全球适应的结果。

英文摘要:

New results in processes with an underlying quark transition $b\to s \ell^+\ell^-$ have been recently reported by the LHCb and Belle II collaborations. In this note we show how the main implications of a handful of new measurements can be understood with the tools introduced in our recent paper, arXiv:1811.10793, without the need to redo the global fits. We find that the main impact of the new results, due to $R_K^{[1.1,6]}$ from LHCb, is a decrease in $C_{10μ}^{NP}$ with a reduced uncertainty. We validate this conclusion by presenting the result of a new global fit.
