Exactly two Jets

p_T > 70 GeV and |eta| <2.5, Veto extra jet with p_T > 50 GeV.

Veto Lepton (e,mu)

e: p_T > 10 GeV ,|eta|< 2.5 Cut Based Electron ID

mu: p_T > 10 GeV, |eta|< 2.4, RelIso< 0.2 Muon ID

Two b-Jets

leading Jets are required to be tagged as b-jets (b-tagger:CSVM)

HT >250 GeV and MET> 175 GeV.

Signal Region

Control Samples

Mu + jets control sample for Top+Wjets estimation.

Same trigger as the signal region.

Invert Mu(RelIso <0.2) veto cut to One tight Mu (RelIso < 0.12).

two b-jets which pass Loose working point instead of Medium working point used in the signal region.

Rest cuts are same as signal region.
