Investigating the flavour anomalies through the rare beauty decay $B^0 \to K^{*0} \mu^+ \mu^-$
We measure the $B^0 \to K^{*0} \mu^+ \mu^-$ decay branching fraction as a function of the di-muon invariant mass squared, using the $B^0 \to J/\psi K^{*0}$ decay as normalisation channel. We use proton-proton collision data at $\sqrt{s} = 13$ TeV, collected by the Compact Muon Solenoid (CMS) experim...
