and open TopQuarkAnalysis/Configuration/test/ in your favorite editor.

Exercise 1

Switch the isolation cone of the muons

  • from 0.4 (default)
  • to 0.3
An example is found, if you follow the parameter pfMuonIsoConeR03 in TopQuarkAnalysis/Configuration/test/ under the assumption that it is set to True .
ALERT! Consider, that here no "postfix" is set

Exercise 2

Include the MVA electron IDs into the PAT electrons. The software is already present in your CMSSW area. You only need to modify this configuration as shown in the example in EGamma/EGammaAnalysisTools/test/

Exercise 3

Apply the veto electron selection, as described here and the conversion rejection on top of it. An example is found, if you follow the parameter electronCutPF in TopQuarkAnalysis/Configuration/test/

Exercise 4

Select only events with at least on electron and four jets. To find the corresponding configuration parameters, run this configuration interactively:

python -i
>>> process.countPatElectrons
>>> process.countPatJets
and modify the parameters you find accordingly. You should see 25 events passing.
