Cuts summary

(The efficiency for signal and background is different only if specified)

The efficiency reported in each subsection refers after the cuts of the previous subsection

Muons

At least 1 $\mu$: Acceptance: 0.954

Trigger cuts:

• abs(Muon_eta[0])<2.4 && Muon_pt[0]>26

Acceptance: 0.756

Identification and isolation

• (Muon_looseId[0] && Muon_pfIsoId[0]>1)

Acceptance: 0.86

Jets

Selected jets

• jet_jetid>0 && jet_puid>0 && Jet_muonIdx1!=0

P_t cuts

• Jet_pt[3]>20 && nJet (after selected jets)>=4

Acceptance: 0.84

btag

• max(Jet_btagDeepFlavB) > 0.2793 (medium)

Acceptance:

• Signal : 0.968

• Background: 0.921

Jet matching

For the signal, after the cuts discussed above:

• $\Delta R_{LHE-JET}&lt;0.4$

  Acceptance: 0.43

• Different Partons match to different Jets

  Acceptance: 0.917

• All the 4 partons are in the firsts 7 jets in pt

  Acceptance: 0.966
