    • ATL-COM-PHYS-2013-1518: supporting note
      • using complicated weighted sum of one or two trigger . It can adds additional ~50% more event trigger efficiency for mjj<1.1TeV. The trigger efficiency is the same after mjj>1.1TeV. The complication because of pre-scale on lower pT jet
      • EF j145 a4tchad ht700 L2FS: one jet with ET > 145 GeV, HT > 700 GeV (HT sum of all jet with pT>45GeV). unprescaled, 99.5% efficient after pT>460 GeV
      • EF j220 a10tcem is 99.5% efficient after pT>333GeV, unprescaled
      • R=0.6 is chosen as baseline since R=0.4 behave similar in terms of significance comparison to q*=400,1000, 2000, 4000
      • pile-up effect is negligible when we select both leading/subleading jet pT>50GeV
        • mjj vs Npv, leadJetPT vs Npv, Njets vs Npv
      • Truth Match Fraction of both leading and subleading jets (reco to truth) are 98% at jet PT=50GeV
      • Reconstruction efficiency is negligible for mjj>50GeV when select both jet pT>50GeV
      • leading jet pT>50GeV and |y|<2.8, subleasing jet pT>50GeV. Event |y*|<0.6 and mjj>250GeV -> spectrum is unbiased by the kinematical cuts on pT
      • if either the leading jet or any of the other jet with pT greater than 30% of the pT of the subleasing jet.
