How to produce ROOT Ntuples

Ntuple Code

Ntuples can be produced using the CMSSW LeptoQuark Ntuple Producer developped by the EXO LQ group. All instructions are given in this good quality twiki.

CRAB Tools

To produce high statistics datasets, it is required to use the GRID and its CRAB interface.

Useful informations are listed in the CRAB FAQ page, CRAB Online Manual. If CRAB jobs are stuck, you can refer to the CRAB Exit Code Twiki to understand the issue.

Done

  • A W_R signal ( M(W) = 1 TeV and M( N ) = 600 GeV ) is now available from the grid and can be used. Copy procedure has been lanched to get data on UMD T3.

Physics checks

Trigger

  • Check the impact of a single isolated muon HLT line
  • Use double lepton HLT line instead of single line
  • Impact of the HLT matching

Leptons

  • Impact of lepton isolation on signal yield : variation of isolation working point
  • Check lepton pT spectra for "signal" events
  • Impact on yield by removing completely Z+jets events (variation/extension) the Z mass veto region

Jets

  • Jet multiplicity
  • pT spectrum when jet is b-tagged
  • Energy spectrum when jet is b-tagged
  • Track multiplicity in jets

B-tagging

  • Which jet is b-tagged preferentially ? The trailing jet is preferentially b-tagged, could be a consequence of the high pT cut made on the leading jet which decreases the b-tagging efficiency ---> Which jet is b-tagged preferentially without high pT jet selection ?
  • Instead of b-tagging jets, try c-tagging
  • All observables with 1 b-tag jet
  • All observables with 2 b-tag jets
  • Variation of the b-tagger used / working point used
  • Link between b-tagging and the kinematics of the jets

MET

  • Transverse mass of the lljj+MET system
  • Transverse mass of the l+MET + jj system
  • Transverse mass of the l+ MET + j system

Lepton+jet combinations

  • DeltaPhi( ll, j1) and DeltaPhi( ll , j2 )
  • pT (lljj) 1fb-1 shown on the 24/11/11 MD weekly meeting, slide 16 nothing special to be noticed until now.
  • Scatter plot : DeltaPhi( l, j1 ) vs DeltaPhi( l1, l2 )
  • Mass( llj)
  • Mass( ljj) requiring only one lepton in the event, and one b tagged jet

WR hypothesis

  • pT( jjl_i ) vs pT( l_j ) : if there is a WR, pTs should be balanced.

LQ pair hypothesis

Fit

  • Is the MC background shape used reproduces well the data ?
  • Try to fit only the background component without signal component
  • Can the e-mu + jj channel be used as a control sample to derive the background shape ? : Even if at a first look one can see the lack of bump in the e-mu channel and think to use this data sample to derive Bkg shape, it cannot be used, due to the lack of Z+jet event in this final state. A possibility is to make a mix of data and MC shapes, or to extrapolate the Z+jet shape from data in a another sample and add it to the e-mu shape.

Uncertainties

  • How much are the systematic uncertainties in the signal region ?
