Efficiencies

Total efficiencies (trigger, reconstruction, analysis) ratio:

• $\varepsilon_{\mu\mu K}/\varepsilon_{KKK} = 0.721 \pm 0.011$;

Ratio of isolation efficiencies:

• $R_{\text{Isol}} = 1.015 \pm 0.014$.
  

Combined acceptance and muon identification efficiency:

• $\langle\varepsilon_\mu \rangle = 0.810\pm 0.021$.
