  1. 10-25 years of DØ France Hugh Montgomery Jefferson Laboratory LPNHE Universite Paris 6 et 7 October 14, 2008

  2. To our hosts Pascal Debu and everyone at the LPNHE Thank you

  3. The Organisers Greg Bernardi, Marc Besancon, Arnaud Duperrin, Phillipe Gay, Pierre Petroff, Isabelle Ripp-Baudot, Gerard Sajot, Patrick Verdier Thank you

  4. To The Speakers Etienne Auge, Frederique Badaud, Ursula Bassler, John Campbell, Marcela Carena, Dima Denisov, Frederic Deliot, Arnaud DuPerrin, Albert DeRoeck, Jos Engelen, Paul Grannis, Sebastian Greder, Jean-Francois Grivaz, Beate Heinemann, Matt Herndon, Karl Jakobs, Eric Kajfasz, Patrice Lebrun, Arnaud Lucotte, Bruno Mansoulie, Klaus Moenig, Christophe Royon, Yves Sirois, Jan Stark, Boris Tuchming, Patrice Verdier, Harry Weerts, John Womersley, Darien Wood, Terry Wyatt Especially to the non-DØ people Thank you

  5. Fermilab Antiprotons

  6. CDF - The Competition

  7. polypropelene foils Xe/CH4 conversion gap Transition Radiation Detector, ret. TRD inside CDC X-ray converter and charge collection chamber Flash ADC time distribution of TRD response to electrons & pions (CERN test beam). Pion rejection > 50:1 Charge clusters from converted X rays drifted to anode wires

  8. Transition Radiation Detector The Scarlet Pimpernel, I failed to find a figure until I collected Paul’s Talk yesterday!!! In Pluquet’s Thesis on the web the figures do not survive into .pdf. But: TRD played a major role in the “weeks of top” and for my association with it, the LHCC declared me a TRD expert and had me give an internal briefing as a precursor to the discussion of the Atlas TRT.

  9. 57pb 19pb Tevatron Run I and Top Dec 94 Aug 93 Yagil – Top Turns Ten

  10. DØ Author List Abachi to Zylberstejn Thanks to all (Grannis), Hadley – Top Turns Ten

  11. Saclay Participation in Top Paper • J. Alitti, • L. Chevalier, • Y. Ducros, • J.F. Glicenstein, • J-F. Lebrat, • B. Mansoulie, • A. Pluquet, • J. Teiger, • A. Zylberstejn

  12. Run II Participation: Saclay and IN2P3 “ Apres moi c’est le deluge!!!” a dit Armand (ou Louis XV ou Mme de Pompadour) Bernardi, Bassler, Petroff, Kajfasz, Sajot, … Clermont Ferrand, Grenoble, Lyon, Marseille, Paris, Orsay, CEA-Saclay, Strasbourg

  13. Run II: The Calorimeter • The heart of DØ needed help • Electronics • Calibration system • Purity Control • ….. Lafayette a l’aide des EtatsUniscontre les Anglais!? • Silicon, and much more

  14. DZero

  15. QCD: Inclusive Jet Production

  16. Physics of the Bs Meson • Introduction • The Bs Meson • More Bs Mesons • Lifetimes and  • Direct CP Violation • Bs Oscillations • CP Violation in BsJ/ • Conclusions

  17. Wb- -> J/Y W- -> J/Y L K- -> (m+ m-)(pp-)K-

  18. Searches for New Phenomena Searches for new particles predicted by many beyond the SM theories: Leptoquarks – generations 1 and 2 (lljj, lnjj) and combined 1,2,3 (nnjj) Susy – squark/gluino in MET+jets, lepton + jets Wino/Zino trileptons, dileptons top squarks bottom squarks GMSB gauginos GMSB photons R-parity violating couplings Right-handed W Heavy W,Z 4th generation b-quark Leptophobic Higgs Large extra dimensions (di-EM, monojets) Anomalous trilinear couplings Magnetic monopoles Model independent searches (SLEUTH) Excellent Run 1 MET resolution key for many searches. Nothing Found!

  19. New Phenomena • Nothing So Far!!!!! • But SUSY is running out of places to hide • Technicolor has not undergone resurrection • The extra dimensions are really rolled up tightly

  20. Vector Boson Production

  21. Summary of the Top Quark Mass Measurements ( 1.2 GeV) M/M = 0.7% F. Déliot, D0-France 13-OCT-2008

  22. Electroweak Fits http://lepewwg.web.cern.ch/LEPEWWG/

  23. Higgs Particle – CDF & DØCombined

  24. Tevatron Luminosity

  25. Efficient Operations: A DØ Hallmark

  26. LHC: A new era to come? • We all look forward to the operation of the LHC with collisions at multi-TeV energies • The cross-sections for known high-mass processes such as top production will increase by a factor of ten from the TeVatron. • The experiments are superbly equipped in this region and higher. • The challenge is the low mass; if the Higgs is very light, finding it will be a challenge, anywhere

  27. Conclusions The decision by the Saclay and IN2P3 groups to participate in DØ for run II appears, in retrospect, to have been the precursor to an explosion of participation from Europe in both CDF and DØ at the Tevatron. It was of great importance for DØ ( and German, UK, other European participation in the Tevatron program) It led to great physics. Nous ne regrettons rien
