Semi-leptonic channel
At first I started off by calculating the missing transverse energy corresponding to lepton neutrino. It was easy to get the MET from some modules, however it would be hard-working to calculate total missing energies and fully hadronic channel is more instructive at the moment.Fully hadronic channel
- Some features :
- Large QCD backgrounds
- Need not to take into account the missing energy (neutrinos)
- Largiest branching ratio ~ 46%
- Two leading jets are considered as b-jets
- b-tagging are not performed in this analysis but it will be taken into account later

Analysis
Jet efficiency
- Tried to make efficiency plots by varying the number of jets in events
- Tried to see the effect of the parameters in analysis.cfg
