Validation of the Gen6 Monte Carlo (4/16/07)

PYTHIA is now the main MC for the mass analysis. We need to compare it with HERWIG to assess if we need to change our model.

Dependencies of Pjet/E(parton) (4-16-06), updated (4-18-07)

Some plots to validate Gen6 plots for the TF's in MC integration. Only events that pass IGV match with chisq<200 are included. These plots are for the q jet from the W. Jet corrected at L5.

Compare HERWIG with PYTHIA

Comparison between HERWIG and PYTHIA are done for GEN5 and GEN6. Comparison of HERWIG-175 gen6 with PYTHIA-178 Gen5 Comparison of HERWIG-175 gen6 with PYTHIA-175 Gen6 Bottom line: HERWIG Gen 6 (175 GeV) compares better with PYTHIA 178-Gen5

Compare Gen6-Gen5 HERWIG, AND PYTHIA Gen6-gen5

HERWIG comparison PYTHIA comparison Bottom line: the difference in the pjet/Eparton we noticed last wednesday is gone. The updated ID94 object in PYTHIA has fixed the problem.
