Description
I will present an improved parametrisation of the contribution of $\bar c c$ real intermediate states in the $B^+ \to K^+ \mu^- \mu^+$ decay,
aimed at improving the description of the dilepton spectrum and, possibly, the extraction of short-distance information from this process. Motivated by B-anomalies,
whose combined explanations calls for large NP in the $b \to s \tau^{-} \tau^{+}$ transition, I will also comment on the possibility of extracting bounds
on this contribution from the $B^+ \to K^+ \mu^- \mu^+$ dilpeton spectrum.
