Kihyeon Cho K. Tollefson FB Asymmetry at Tevatron

Kihyeon Cho 8 We used dimension-6 four quark operators with all the possible Dirac and color structures. We considered the s-, t- and u- channel exchanges of spin-0 and spin-1 particles whose color quantum number is either singlet, octet, triplet or sextet. Our results encode the necessary conditions for the underlying new physics in a compact and an effective way when those new particles are too heavy to be produced at the Tevatron. FB asymmetry at Tevatron Model independent analysis S.-h Nam. et.al, PLB 691, 238 (2010) The region in (C1,C2) plane that is consistent with the Tevatron data at the one sigma level.

Kihyeon Cho Collaboration between France Group and KISTI Meeting between KISTI and France Group Every Monday night 9:30-10:30 PM by SKYPE since July, 2010 Dr. Youngjin Kim visited Paris to work on Bs physics between August 8~20. 24

26 Ongoing with Paris group Analyzed 5.2 fb -1 Including new trigger (TTT) => adds 25% more data New analysis => cross-check Optimized data selection => getting more data than just from multiplying with the increase in luminosity. Untagged analysis in progress with TTT and comparing with Dimuons J/Ψ→ μμ from TTT sample Bs→J/Ψφ from TTT sample 6500 events from dimuon sample now Youngjin Kim, K. Cho, Aurore, Nidal, etc.

July 6 th, Data Preselection for B s  J/ Decays N. Ershaidat N. Ershaidat LPNHE – Paris CDF Team CDF Paris – CDF Korea Meeting Sabbatical Leave from: Physics Dept. Yarmouk Univ. Irbid Jordan

July 6 th, CDF standard selection: Please refer to CDF Note 10056:

July 6 th, Procedure – Selection Criteria Dimuons/TTT Data Stream Dimuons/TTT Data Stream BSTNtuples CDF Standard Selection of Bs→J/Ψφ CAF Production of our own ROOT files with compressed info for all selected dimuon candidates Applying our selection and CDF goodrun list FITTER Analysis of selected Bs candidates: M(Bs), M(J/Ψ), M(φ), cτ.. in order to cross-check and better tune the selection cuts

July 6 th, Datasets Output files (.root files) stored on lpnp24.in2p3.fr The stored files size is roughly 1 TB

July 6 th, MC Production Status R. Tesarek’s procedure for MC production of TTT events works smoothly and rather well LPNHE is at the NTUPLING phase. Collaboration with KISTI will certainly accelerate the process

July 6 th, LPNHE & KISTI Once the SAM Station is installed, KISTI & LPNHE can use the KISTI Grid for the production of data as well as MC files. => Waiting for SAM Station at GSDC A double copy of the.root files can be stored in both places.

July 6 th, Status and Plan 2- Production of relevant ntuples (.root files) for the reconstruction of the signal for both data streams. =>waiting for disk space 2- Production of relevant ntuples (.root files) for the reconstruction of the signal B s  J/  for both data streams. =>waiting for disk space Collaboration Scheme 3- Production of MC ntuples (.root files) of the decay for the Two Track Trigger data stream. => doing 4- Creation of a common space (KISTI & LPNHE) for the use of the resulting files (Estimated size: few (~3-4) TB for the expected 10 fb Unification of the tools used. Take into account the operating systems (SLF 5: recommended). =>done => See Youngjin’s talk

Kihyeon Cho Summary New CDF members of KISTI are welcome. HEP team at KISTI contributes to CDF by paradigm of e-Science for top physics and Bs physics. We work on remote control room and FKPPL very well.

Kihyeon Cho Thank you. 36
