W + Jets Analysis

• First, set up CMSSW 160 as described in CMSSWSPRACE
• Create an EDAnalyzer: (describe how to do it)
• Copy the EDANalyzer to the src directory
• scramv1 b
• Copy the Configuration Fragments w0.cff, w1.cff, ..., to the share directory
• Copy the Configuration Files w0.cfg, w1.cfg to the main directory
• Copy this ROOT macro: agrupar_pt30_R05.C to the main directory
• Run all the Configuration Files: cmsRun w0.cfg , ...
• Run the ROOT macro: root -lq agrupar_pt30_R05.C
• Plot the resulting file with ROOT: root -l allw_ic_pt30_R05.root, and select the wsum histogram. Plot it in log scale to see that the log of number of events with N jets is a linear function of N.
