PHY905 - Project 6

Steps of Analysis

Step 1:	Generate W=>e+nu events using Pythia	script
Step 2:	Run SpartyJet jets on pythia output	script
Step 3:	Rerun steps 1 and 2 for "detector" level	script
Step 4:	Run simple analysis script to make histograms of jets, W's, leptons and missing Et	script
Step 5:	Rerun above steps substituting W=>e+nu+1 parton for the W=>e+nu generation	See comments in SpartyJet scripts above

Note I wrote a combined script in which the pythia event generation (Step 1) and jet finding(Step 2) are done in the same script. This is possible using the new SpartyJet feature "PythiaInput". Alternatively, one could generate events in Pythia, save as HepMC, and then run SpartyJet on the HepMC file. Using PythiaInput requires this new SpartyJet and a ROOT installation linked to pythia8
