17. The Physics Project - top - Bs 17

18. 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 τ ν τ 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

27. 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/ψ Φ: 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/ψ Φ, 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

45. 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). 45

46. 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. 46

47. 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. 47
