Hypothetical Feynman diagrams of $\Bds \rightarrow \proton \ell^{-}$ mediated by a hypothetical $Y$ boson.

-

Expected distribution of the MLP response for \BdsTopmu decays as obtained from the \BdToKpi control channel, for (left) Run 1 and (right) Run 2 data. The total (statistical and systematic combined) uncertainty is shown as a light grey band, and the thickness of each horizontal line at the centre indicates the statistical uncertainty. Each interval is normalised to its width.

Mass distribution of \BdToKpi candidates in data for (left) Run 1 and (right) Run 2. The results of the invariant mass fits are superimposed.

Comparison of the distributions of the \Bd vertex fit \chisq ($\chi^2_{\mathrm{fit}}(B^0)$) and the minimum \chisqip of the two tracks in the final state ($\mathrm{Min}(\chi^2_{\mathrm{IP}})$), for the same-sign sample and data sidebands in Run 2.

Results from the CLs scan used to obtain the limit on (left) $\BR(\BdTopmu)$ and (right) $\BR(\BsTopmu)$. The background-only expectation is shown by the red line and the 1$\sigma$ and 2$\sigma$ bands are shown as light blue and blue bands respectively. The observation is shown as the solid black line. The two dashed lines intersecting with the observation indicate the limits at 90\% and 95\% CL for the upper and lower line, respectively.
