Please bring your laptop. We will continue working with the jet event example in the ROOT tutorial section today.


  • Start from the jets.C TTree loop and add the option of filling histograms with info from the JetEvent class. Also add the possibility to cut on quantities like e.g. the number of tracks per event, the pt of jets, etc. Upload your work i.e. .C files, etc. as usual beforethe next lecture to this area. Important: Do not use anywhere the SetBinContentmethod or the TTree:Draw(..) method.
  • Write and define your own ROOT style, etc. and put all your enhancements into your standard rootlogon.C file.
  • Give us details about H->ttbar channel shown in the plot we discussed in the lecture. The plot can be found in this publication.
