\small Invariant mass distributions for (a) \BsToDphi, and (b) \Bz\Dzb\Kstarz or \Bs\Dzb\Kstarzb decays. Data points are shown in black, the total fitted PDF as solid black line, and the components as detailed in the legends.

\small Distribution of the cosine of the helicity angle of the ϕ candidates.
\small Background-subtracted distributions of the reconstructed (left) \Pphi mass from the \BsToDphi decay and (right) \Kstarzb mass from the \BsToDKstar decay. The dashed red line represents the S-wave component, the solid blue line the total fit result.
