Book excerpt: The decay $ \mathrm{B}^{+} \to \psi(2 \mathrm{S}) \phi(1020) \mathrm{ K }^{+} $ is observed for the first time using data collected from pp collisions at $\sqrt{s} = $ 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb$^{-1}$. The branching fraction of this decay is measured, using the mode $\mathrm{B}^{+}\to \psi(2 \mathrm{S}) \mathrm{ K }^{+}$ as normalization, to be (4.0 $\pm$ 0.4 (stat) $\pm$ 0.6 (syst) $\pm$ 0.2 ($\mathcal{B})$)$\times$ 10$^{-6}$, where the third uncertainty is from the imprecision in the normalization channel.
