Description
I will first discuss a possible parametrisation of the contribution of two-particle intermediate $\bar c c$ states (open charm threshold) to the $B^+ \to K^+ \mu^+ \mu^-$ differential decay rate. Motivated by $B$ anomalies, whose combined explanation calls for large New Physics in the $b \to s \tau^{+} \tau^{-}$ transition, I will then comment on the possibility of extracting a bound on this contribution from the $B^+ \to K^+ \mu^+ \mu^-$ spectrum.
