论文摘要
LHCB协作最近提出的decay $ b \ to k^* \ ell^+ el^ - $的新角度分析仍然表明了与标准模型预测的某些紧张关系。正在进行几项分析，以解决在这种衰变中分离辐射和新物理作用的问题，但是在$ b \ to $ b \ to K^*μ^+μ^ - $中观察到的紧张局势的重要性仍然取决于对这些衰变的理论猜测对这些衰变的理论猜测。使用LHCB的新数据，我们提供了两项测试，这些测试可以进行统计比较，以确定对异常的最喜欢的解释是新物理学还是低估的HADRONIC效应。然后，我们在两个将来的情况下分析了这些测试的有用性。最后，我们将全局拟合更新为所有可用的$ b \ tos s $数据，并讨论新的LHCB测量结果的影响。
The new angular analysis of the decay $B \to K^* \ell^+ \ell^-$ recently presented by the LHCb Collaboration still indicates some tensions with the Standard Model predictions. There are several ongoing analyses to solve the problem of separating hadronic and New Physics effects in this decay, but the significance of the observed tensions in the angular observables in $B \to K^* μ^+μ^-$ is still dependent on a theory guesstimate of the hadronic contributions to these decays. Using the new data from LHCb we offer two tests which make a statistical comparison to determine whether the most favoured explanation of the anomalies is New Physics or underestimated hadronic effects. We then analyse the usefulness of these tests in two future scenarios. Finally, we update our global fits to all available $b \to s $ data and discuss the impact of the new LHCb measurements.
