Resonances gone topsy turvy - the charm of QCD or new physics in $b\to s{\ell }^{+}{\ell }^{-}$?

James Lyon, Roman Zwicky

We investigate the interference pattern of the charm-resonances $\Psi (3370,4040,4160,4415)$ with the electroweak penguin operator $O_9$ in the branching fraction of $B^{+}\to K^{+}\mu \mu$. Fo…
