Hadronic W decay in new version of PAT CMSSW_3_3_5

All of these using this event selectionEvent Selection - Electron pT > 20 GeV/c - Electron Isolation < 0.1 - Standard Electron Identification - Electron abs(eta) < 2.5 - Missing Transverse Energy > 20 GeV

M(jj) Reconstruction - Jet pT > 30 GeV/c - HighEfficenecy b tag < 2.03 - ΔR(jj) > 0.5

1

The differences between CMSSW_2_2_9 and CMSSW_3_3_51. Different jet algorithm i.e. IC5 on 229 and Anti-KT on 335

2. Some changes in the calorimeter calibration in the simnulation

3. Some changes in ECAL energy scale

4. Also, 335 have cleaning by default but 229 need to add cleaning module (SUSYPAT)
