【 摘 要 】

In this article a recent work is reviewed, where we evaluated the impact of radiative corrections in RKand RK∗. We find that, employing the cuts presently applied by the LHCb Collaboration, such corrections do not exceed a few percent. Moreover, their effect is well described (and corrected) by existing Monte Carlo codes. Our analysis reinforces the interest of these observables as clean probe of physics beyond the Standard Model.
