Table 2.

Average number of selected candidates per event (efficiency) in % for different ${\mathit{\pi }}_v$ masses, lifetimes and decay modes. The reported uncertainty is only the statistical uncertainty from the finite sample size. No simulated samples were generated for the 100$\mathrm{ps}$ decay to light quarks
