Monte Carlo Validation
Goal
To write a package to do streamline Monte Carlo Validation. Action items:
- Things to check for top:
- W(qq) inv mass
- W(lnu) inv mass distinguishing the three possible flavors
- top (qqq) inv mass
- top (qlnu) inv mass
- dN/dn_genjet
- 1st and 2nd associated jet pT and eta
- branching ratio of ttbar decays (had vs semilep) vs ttbar
- Things to check for Z and W
- All similar, except the top mass of course.

CVS
The code is structured as an EDAnalyzer, located at the SPRACE CVS repository.
export CVSROOT=/hdacs/shared/cvsrepository
- Check out the code - make sure to be inside a directory
CMSSW_X_Y_Z/src/SomeAnalyzer
beforehand!
cvs co ValidationAnalyzer
- Check in the code after making changes.
cd CMSSW_X_Y_Z/src/SomeAnalyzer
cvs ci ValidationAnalyzer

Log da Flavia
- To reconstruct t and tbar, I located the vertice that have a t (tbar) ingoing, and took the outgoing particles of the vertices. However, some of these top vertices got also other particles than the W and b: uubar, gluon. I've (under Thiago advice) just ignored it and tried to reconstruct the top mass with just W's and b's. Solved: status 2 particles.
- Status stuff - status 2 particles for showering.
