Synchronization exercise for th(bb) analyses

Main twiki can be found at SingleTopHiggsBB.

Objects are defined at SingleTopHiggsBBEventSel.

Modification of objects definitions and event selection

Although definitions of physics objects and reference event selection are provided in SingleTopHiggsBBEventSel, several simplifications are adopted in the context of synchronization exercise in order to allow a gradual evolution of the setup. The following changes are made in the first iteration of the exercise :

  • No filters to reject anomalous or noisy events are applied. The only event filter considered is the selection on properties on the first primary vertex
  • Loose electrons are defined using PF-based momentum instead of the ECAL-based one
  • No jet smearing to mimic JER in data is applied
  • No PU jet ID is applied
  • MET is ignored completely
Beside the simplifications mentioned above, event selection is different from the reference one in few aspects:
  • Jets are not subjected to selection on b-tagging
  • Threshold on jet transverse momentum used for jet counting is 30 GeV/c

Selection Steps

Muon Channel

Step Selection Comments/details/code snippets
0 trigger  
1 exactly one isol. muon exactly one muon passing the selection
2 loose muon veto Reject events with any other loose muon.
3 loose electron veto Reject events with any loose electron.
4a,b,c,d >= 1,2,3,4 jets for jets passing the event selection.

Electron Channel

Step Selection Comments/details/code snippets
0 trigger  
1 exactly one isol. ele Exactly one isolated electron passing the selection.
2 loose muon veto Reject events with any loose muon.
3 loose electron veto Reject events with any other loose electron.
4a,b,c,d >=1,2,3,4 jets for jets passing the event selection described in the section

Additional constraints

to be added.

Synchronisation over simulation (signal process)

The following root file is used for synchronization:

/store/mc/Summer12_DR53X/TTJets_SemiLeptMGDecays_8TeV-madgraph/AODSIM/PU_RD1_START53_V7N-v1/10000/8425E88A-AED7-E211-8067-002481E14F5C.root

The file can alternatively be found under:

/afs/cern.ch/user/s/sfink/public/8425E88A-AED7-E211-8067-002481E14F5C.root

Synchronisation is to be performed with global tag START53_V27 (as recommended here).

Properties of individual objects in events

In addition to the cut-flow table, you are invited to share details about various reconstructed objects in an event (momenta, isolations, IDs, etc). Process the following events from the synchronisation file:

'194533:34578326', '194533:34578375', '194533:34578400', '194533:34578466', '194533:34578529',
'194533:34578306', '194533:34578348', '194533:34578365', '194533:34578371', '194533:34578379'

Event IDs are provided in the form runNumber:eventNumber (as expected by VEventRange). The first line lists some events that pass the full selection in the muon channel, the second line mentions events from electron channel.
