means to type in ROOT

Copy GitHub Repository:

git clone https://github.com/zflowers/TimingMETSearch 

Create ROOT files from LHE files

Copy or Move LHE file to ExRoot Directory

 > ./ExRootLHEFConverter NameOfFile.lhe NameOfFile.root 

To analyze ROOT file after moving the root file and lhe file back to the old directory using ROOT

 [] new TBrowser 

Navigate to the root file that you would like to analyze. Or launch root using

 > root -l NameOfFile.root 

Next run .C macro in root

[] .x NameOfFile.C
[] NameOfFile m
[] m.GetEntry(0)
[] m.Loop()
 

The files in the GitHub repository will output either trees or histograms

The recommended way to run this code is to first create all of the root files from the lhe files. There is a lhe file in each directory and these are run through ExRoot to generate the root ntuples. Next these root files can be run through any of the macros to generate a desired result. The files named "jet??.C" are for recreating a root file with histograms. This outputted root file can be looked at with "Analyze.C" to make plots comparing different attributes of the trees. "??" corresponds to the maximum possible number of jets added onto the process. So 0 means there are no jets, 01 means there could be 0 or 1 jet, and 012 means there could be 0, 1, or 2 jets added onto the process.

The delphes_1jet.C file will create a tree from the pythia MC process and the delphes RECO simulation. This more compact tree can be used with Analyze_n2n2j.C to create histograms of the event. We use this to look at the delphes smearing of events.
