  15. Aurore’s visiting Korean Institutes on March 2010 • March 15 – KIAS, Seoul • For collaboration with phenomenologists • March 16 – SNU, Seoul • March 17 – KNU, Daegu

  16. The Physics Project - top- Bs

  17. Developing common interest in Top/Higgs searches • Both Korea and France have been working on top Physics: => top into dileptons (Korea) => top into dilepton including one τ lepton (France) => single top (Korea and France) • We are developing a common research project: based on the acquired experience of both teams on top Physics; focused on the study of top pairs into τ leptons and as by-product the search for Higgs into τ pairs and charged Higgs into τντ This common research will bring an interesting breakthrough with the data recorded with the total Tevatron Luminosity (may be even a discovery if the τ-channel is favoured ?) and it will be instrumental for the LHC. =>Need of large amount of MC production (KISTI and CCIN2P3) and we also intend to include now data handling in both centers.

  18. Status of Top physics • Single top • Top into dileptonic • 2 taus • Dileptonic • MT2 method (by phenomenologist) • ttbar forward-backward asymmetry (by phenomenologist)

  26. B Physics common searches • Physics stream • B physics with different data based on   and 2 track triggers mainly for Bs Mixing (CDF discovery in 2006) pursuing since two years on CP violation studies in the Bs sector • Same physics streams • Bs → J/ψΦ: CP violation related studies • CP even and odd measurement: sin2βs (France) (started by G.P. di Giovanni and A. Savoy-Navarro now continuing with N. Ershaidat and soon A. Savelyeva and V. Saveliev) • B → J/ψ K*0 competitive results with Babar/Belle (France) • Bs → J/ψΦ, ψ(2S) Φ (Korea) • Bs → J/ψ Φ, using new PID (dE/dx andTOF) and TTT (Two Track Trigger) => sin2βs (France) => The Bs sector is crucial Physics for searches beyond standard model.

  27. Status of Bs physics • CPV in Bs physics • Bs -> J/psi phi • Dimuon (DIM) Sample • Two Track Trigger (TTT) Sample • Bs -> J/psi phi pi pi

  31. Signal – (All Cuts) mBs = 5.366  0.0002 GeV/c2 mBs = 5.366  0.0002 GeV/c2 • Bs -> J/psi phi (TTT) • Bs -> J/psi phi (DIM) One should compare these two plots! N. Ershaidat

  41. The contents of Collaboration • We have exchanged visitors in 2009. • Aurore visited Korea on Feb. 15~19. • Kihyeon visited France on Feb 24~28 and June. • 7 Korean CDF members have visited LPNHE, Paris on June 28-July 2. • We have performed analysis in close collaboration(ex. Top & Bs physics).

  42. The Contents of Collaboration • We have done one offline-workshop and two video-conferences. • We have communicated with a lot via phone or EVO. • We collaborate together for the publication in journals and a book. • Both of us are working together with phenomenologist.

  43. Plan • We will host a workshop every year • June 28~30 2010, The 2nd France-Korea CDF Physics Workshop @KNU, Daegu, Korea • Half-day video conference meeting once per quarter 3:00 PM (Korea Time) • For student, we consider double degree. Or after getting his/her Ph.D we consider him/her about European fellowship.

  44. Thank you.
