Description

Rare semileptonic $b\to s{\ell }^{+}{\ell }^{-}$ transitions provide some of the most promising framework to search for New Physics effects.
Recent analyses have indicated an anomalous pattern in measurements of lepton-flavour-universality observables.
We propose a novel approach to independently and complementary clarify the nature of these effects
by performing a simultaneous amplitude analysis of $B^0\to K^{\ast 0}{\mu }^{+}{\mu }^{-}$ and $B^0\to K^{\ast 0}{e}^{+}{e}^{-}$ decays.
This method allows the direct determination of the difference of the Wilson Coefficients ${\mathcal{C}}_9$ and ${\mathcal{C}}_{10}$ between electrons and muons,
and are found to be insensitive to both local and non-local hadronic contributions.
We show that considering the current preferred New Physics scenario a first observation of LFU breaking in a single measurement is possible with LHCb Run-II dataset.
