The Physics Project - top- Bs

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 ντ

This common research will bring an interesting breakthrough withthe data recorded with the total Tevatron Luminosity (may be

even adiscovery 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.

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.04/21/23 CDF-LIA, FKPPL in Lyon, 2009
