  1. Comparison between 1st and 2nd analysis • 1st analysis was using code and instruction from https://twiki.cern.ch/twiki/bin/viewauth/CMS/ZJetsAndDPS and reported the result at http://highenergy.phys.ttu.edu/~keng/susy/plots/Zjets_2012Full.pdf ***use pfNoPileup and remove leptons from jet reclustering • 2nd analysis is independent analysis suggested by Kostas and Ann-Marie and reported the result at http://highenergy.phys.ttu.edu/~keng/susy/plots/Zjets_2012Full_KengCode_021913.pdf ***Do not use pfNoPileup and do not remove leptons from jet reclustering
