Description
Rare semileptonic $b\to s\ell^+\ell^-$ transitions provide some of the most promising framework to search for new physics effects. Recent analyses of these decays have indicated an anomalous behaviour in measurements of angular distributions of the decay $B^0\to K^*\mu^+\mu^-$ and lepton-flavour-universality observables. Unambiguously establishing if these deviations have a common nature is of paramount importance in order to understand the observed pattern. In this talk a novel approach using a simultaneous amplitude analysis of $\bar{B}^0 \to \bar{K}^{*0} \mu^+\mu^-$ and $\bar{B}^0 \to \bar{K}^{*0} e^+e^-$ decays is discussed and prospects for this measurement at LHCb are shown. If current hints of new physics are confirmed, this analysis could allow an early discovery of physics beyond the Standard Model with full LHCb Run-II datasets.
