  1. Gen 5 MC validation…( top mass template ) • Rec. Mtop - Pythia 5.3.2 vs 4.11.1 (-0.9) - Herwig 5.3.1 vs 4.11.1 (-0.7) - Herwig 5.3.2 vs 4.11.1 (+3.3) - but Mtop=178 for 5.3.2 Pythia and Herwig • What is wrong in Pythia 5.3.2? - Herwig (Mtop: 175->178) 2% up, Pt(W,b) - Pythia (Mtop: 175->178) 2% up for Pt(b), 2% down for Pt(W) Mtop=170.6 Mtop=173.9 Mtop=170.6 Mtop=169.9 Mtop=170.9 Mtop=170.0

  2. Gen 5: Top mass tempalte anal.(Herwig) b-tag eff. is reduced by 15%, Does this mean that scale factor is now closed to 1?

  3. Herwig 6.504 + Photos( for10k ttbar events) t->bg uds W(mainly lepton channel)
