Measurements of $R(K)$ and $R(K^*)$ with the full LHCb Run 1 and 2 data
<!--HTML--><p>In this seminar we present the first simultaneous test of muon-electron universality in $B^+ \to K^+ \ell^+\ell^-$ and $B^0 \to K^{*0} \ell^+ \ell^-$ decays, known as $R(K)$ and $R(K^*)$, in two regions of di-lepton invariant mass squared.<br>The analysis operates at...
