  1. MC Production status

  2. Part 1 : problems with Z, W production Final Words ?

  3. Problems remaining • We don't get the expected number of events for ... • W+4jets • Z+3 and Z+4jets (Drell-Yann and Z> nu nu) • problem reported in a MG bug report : no answer • Though no prob for the other jet multiplicities • In the following: • tests that have been carried • solutions suggested  = prescription to follow for the prod

  4. W+jets • No problems for 0,1,2 and 3jets • Problem appears for exp number > 50k • For W+4jets: • tried: • Detail the proc_card (e.g. split the leptons) ✖ • Multigridpack : split in quarks from gluons in the final states ✖ • Cut on drLL,drLj✖ • Suggested solution: • Produce 20k events a job

  5. Z+3j (10<mmll<50) • No problems for 0,1 and 2 jets • Problem appears for exp number > 50k • For Z+3jets: • tried: • Detail the proc_card (e.g. split the leptons and jets) ✖ • Cut on ptj, pta, drjl, mmjj, ptl✖ • Cut on drll (>= 0.15) ✔ • Suggested solution: • Impose minimum drll >= 0.15

  6. Other Z+jets • Z+4jets (mmll>= 50): • split proc_card✖ • cut on drll ongoing • Suggested solution: • Produce 20k events a job • Z+4jets (10 < mmll < 50): • No test carried • Suggested solution: • Produce 20k events a job • Z > nu nu +3jets (idem for 4 jets) • Only tested splitting proc_card✖ • Suggested solution: • Produce 20k events a job

  7. Part 2 : photon production Final Words ?

  8. Summary of private discussion with Greg • Gamma samples relevant for t-gamma-q FCNC coupling and Higgs analyses • List of samples to do : • A+jets, AA+jets, WA+jets, ZA+jets • TT+A, TT+AA • TAq • Some quick-and-dirty-produced samples are available for preview.

  9. Required samples

  10. Summary of private discussion with Greg List of actions: • Fucking merging study : • Strasbourg : A+jets, WA+jets, ZA+jets • IIHE : TT+A, TT+AA, AA+jets • Lobster eats Scampi! Loster step 0 is available. • Inclusive production : • Strasbourg : WA+jets, ZA+jets, TAq • IIHE : TT+A, TT+AA • Exclusive production : • Strasbourg : A+jets • IIHE : AA+jets • Improvement of Delphes-MA5tune reconstruction of photons(complementary to Taejeong’s study) • Step 3 could be redone for all the production in some days

  11. Summary of private discussion with Greg Configuration (inspired of CMS cards): • pta > 10 GeV • draj > 0.01 • drab > 0.01 • draa > 0.01 • maa> 50 GeV(if 10-50 GeVneeded, produced after)
