Z_KK to ZH analysis with delphes ntuples

  • Code for the Z_KK to ZH decay analysis is on titan in /home/willocq/Snowmass2013/root/. Create a work directory named Z_KK and copy the contents of the original directory into it:
    • cd
    • mkdir -p root/Z_KK
    • cd ~/root/Z_KK
    • cp /home/willocq/Snowmass2013/root/*.C .
  • Create a link to an include file required for compilation
    • mkdir classes
    • cd ~/root/Z_KK/classes
    • ln -s /scratch/willocq/Snowmass2013/Delphes-3.0.9/classes/SortableObject.h
  • Run the analysis code
    • cd ~/root/Z_KK
    • root -b -q runMyExample1.C
  • A series of histograms is produced and stored in an output file with a name specified in runMyExample1.C, it’ll be of the form output_filename.root, where filename is the name of a given input file. The input files are stored inĀ /scratch/willocq/Snowmass2013/Delphes-3.0.9/.
  • The histograms can be plotted with the help of the myPlots.C macro; for example start up root and give it the histogram file name as input, as follows
    • root output_filename.root
  • At the root prompt you can then execute the plotting macro, which actually runs a number of functions defined in myPlots.C
    • .x runMyPlots.C
