  1. WWg/WWZ verticesStatus of TGC paper S. Jézéquel (LAPP) S. Jezequel (LAPP)

  2. Previous 'publications' • Measurement of Triple Gauge-Boson Couplings at LEP energies up to 189 GeV:Eur. Phys. J., C 21 (2001) 423 • Measurement of Triple Gauge-Boson Couplings in e+e- collisions up to 209 GeV : Summer conf. 2003 • Thesis of R. Bruneliere People still in the game • S. Jézéquel (W+W- OO method +single W + combination) • T. Barklow (W+W- likelihood method + CP violating/conserving couplings) S. Jezequel (LAPP)

  3. W+W- analysis • Standard 3 couplings ( Dg1z, Dkg, lg) measured with Optimal Observable • Need to rerun with the last reconstruction (small change foreseen) S. Jezequel (LAPP)

  4. W+W- results (conf note 03) Stat.+Syst. g1z=1.030+0.035-0.034 Dkg=1.029+0.097-0.082 lg=0.014+0.034-0.033 S. Jezequel (LAPP)

  5. W+W- results systematics • O(a): • Dominated by Racoon/YFS difference • (Work of F. Cossutti (DELPHI)) • Same amplitude as O(a) itself S. Jezequel (LAPP)

  6. Likelihood method • Individual parameters S. Jezequel (LAPP)

  7. Likelihood method(2) • Techni-rho • Form factor (FT) • Mass/Width Mr>625 GeV S. Jezequel (LAPP)

  8. Single W • Extension of the cross section work • Remove single W already selected as WW (mainly as tnqq) • Use Koralw efficiency + LEP cross section (relevant for qq) S. Jezequel (LAPP)

  9. Single W(2) S. Jezequel (LAPP)

  10. WW+single W/g : 1D Stat.+Syst. g1z=1.030+0.035-0.034 Dkg=0.990+0.072-0.068 lg=0.014+0.033-0.032 Single W will change S. Jezequel (LAPP)

  11. WW+single W/g : 2/3D S. Jezequel (LAPP)

  12. Supposed to be already written • Selection from the WW cross section and single boson cross section papers • Reconstruction in the W mass paper Already explained in 189 GeV paper • Optimal Observable method • No change for single g analysis S. Jezequel (LAPP)

  13. Items to be put in the final TGC paper • Description of the likelihood method (T. Barklow) • Shift from OO1+iteration to OO2 • Single W new MC (efficiency)+remove already selected as WW • Use the same reconstruction as W mass for consistency but no sensitivity S. Jezequel (LAPP)

  14. Time scale • As soon as possible • Finish the single W analysis • Recheck all WW systematics ( almost already done) • Paper should be finished before La Thuile S. Jezequel (LAPP)
