| \small (top) Mass distribution of the selected \Bmm candidates (black dots) with ${\rm \BDT}>0.55$. The result of the fit is overlaid together with the \Bsmm (red solid line) and the combinatorial background (blue dashed line) components. (bottom) Background-subtracted \Bsmm decay-time distribution with the fit result superimposed. |
| \small Mass distribution of the selected \Bmm candidates (black dots) with ${\rm \BDT}>0.5$. The result of the fit is overlaid, and the different components are detailed. |
