24. Beyond CDF: launching a new proposal WHY? A number of facts have lately occurred: Shutdown of the Tevatron Program in 2011 Impressive LHC running conditions and Postponing from 2012 to 2013 the one year LHC shutdown Aurore is moving to another Laboratory

25. Si TevatrOn Run III No? Finance issues Politics Manpower Detector aging Scientific motivations Impact on the FNAL future Over the last year, both CDF and D0 collaborations carried on a lot of work & discussions and meetings with the US authorities (DOE) to extend 3 more years the Tevatron Run: Run III TEVATRON END

26. Tevatron is breaking records: FY2011: 0.75fb-1 till 13/1/11 Peak Lum: 3.2-4.0x10 32 cm -2 s -1 Weekly Integrated Lum: 80 pb -1 Tevatron is running better than ever 02 06 08 07 10 09

27. Tevatron's holiday gift: two milestones in one week The Accelerator Division achieved two new records for the holidays. During the week of Dec. 21, the Tevatron set a record for the number of store hours: 151.25. The complex produced physics data during nine stores for a total of 151 hours. The plot above shows how little time passed between each store. During that same week, the Antiproton Source produced a record number of antiprotons, equivalent to 4,033 milliamps.

29. THE LHC IS DOING IMPRESSIVELY WELL !!!

30. LHC running in 2011-2012 In 2011, Instantaneous Lum is expected to reach up to 2 x 10 33 cm -2 s -1 and a total Luminosity of 2 fb -1 delivered per experiment In 2012, Inst. Lum is expected to reach up to 5 x 10 33 cm -2 s -1 with a total Lum up to about 8-10 fb -1 delivered per experiment The one year-shutdown is postponed to 2013. Impacts of Bs and Higgs sectors reach

31. Forthcoming B s Physics results at LHC In most B Physics channels, LHCb very soon wins: 1) B s →μ+μ- (KNU) New CDF results presented at Winter conferences Sensitive to SUSY Higgs (ex M A =600 tgβ~30) Similarly in the study of CP-violation in the Bs sector (see next)

32. LHC: Low mass Higgs discovered in 2 years from now ? updated CMS NOTE-2010/008 VERY TOUGH!! but if low mass Higgs, with hard work on analyses and on the accelerator…we may get it!

33. LHC vs Tevatron: Higgs sector 3σ3σ 5σ5σ 5 fb -1 at 8 TeV => 3σ for 114 to > 500 GeV Tevatron aims to 2.4σ exclusion in 100-185 GeV by end 2011….. BUT E.c.m. (& smart experiments) win! ATLAS & CMS estimated Higgs sensitivity if 8 TeV Hard work pays!!

34. Aurore is moving to APC Laboratory APC is hosted in Uni. Paris Diderot and is part of CNRS-IN2P3

35. Close relations with Korea: Only french U. with Licence degree in Korean Language and Culture The president of U. Diderot Paris: instrumental for restituting the Korean Royal Manuscripts Korea will build a korean garden on Uni. roof University Paris Diderot:

36. Close contacts Korea and APC: P. Binetruy Lab director’s visits Experiments and G. Smoot Nobel Prize G. Smoot (Berkeley U.) is: Prof. at U. Paris Diderot and Director of IEU (institute for The Early Universe) EWHA U. Thus we are encouraged to pursue and further develop our collaborative efforts, in this new context University Paris Diderot: Les Grands Moulins APC Buildings in Paris XIII

37. Beyond CDF: launching a new proposal We decided to change our collaboration goals => 2011 = transition year We thought essential to keep the positive momentum that we succeeded to build over these last 2 years. This is why we didn’t want to stop this LIA action but instead to keep the fruitful collaboration framework and friendly links it created, in order to further expand it and build a new proposal Due to a number of facts that lately occurred: Shutdown of the Tevatron Program in 2011 Impressive LHC running conditions and Postponing to 2013 the one year LHC shutdown Aurore is moving to another Laboratory

38. Achieving the Bs-CPV analysis by Summer Results with full statistics and where we add a new data stream from a powerful trigger: Two Tracks trigger (see next slide). Developing further the R&D on Si detectors: generic R&D for future experiments & applications to Medical imaging (already existing collaborative work on generic Silicon R&D to be further developed) Investigating common Physics interests: experimentalists x theoreticians Beyond CDF: launching a new proposal HOW ?

39. Achieving the Bs-CPV Kr-Fr analysis The unique features of the analysis we developed to study Bs-CPV in the process: Bs→J/Ψφ are: Detailed and unique analysis of the Two Track Triggers (TTT) in CDF (14 different TTT trigger paths) and of their evolution over the full run II period = 10 Years (trigger algorithm changes and luminosity increase) Dedicated and new TTT MC and full simulation studies (note here a collaborative effort established with Tsukuka U. on this respect). New ROOT Fitter to analyse data and extract the results Same analysis method applied to both data streams: dimuons and TTT and ready to combine them. Still competitive until Summer conferences Legacy: analysis method and powerfulness of triggers (especially Si tracking based triggers) In the pipe: Internal Notes and towards June blessing of results & preparation of Publication over this summer.

40. Level-3 trigger We carried on a unique study on the TTT In CDF; the aim was to well understand the content of these selected data. One important result: the TTT does not include PID => one has to revisit the decay Parameters as selected by TTT/Offline reconstruction First time TTT is used for not purely hadronic signatures

41. Fitter: Mass distribution (gaussian + exponential) Full CP final states angular analysis cτ error (sum of gamma functions) Dilution (from sidebands and background subtracted data) Tagging and tagging efficiency (ready to include it) TTT Bs mass TTT data TTT MC YJ.Kim (collaborative effort with Tsukuba, H. Miyake)

42. Already long term collaboration with Pr. Hwanbae Park (KNU): last year visit ASN at KNU (March) and contributions to the France-Korea Workshop at KNU (June), also extended to other Korean Institutes* *Korean Universities around KNU & ETRI KEK & Tokyo U. Hamamatsu HPK

43. Beyond CDF a new proposal: Pursuing our weekly Bs-CPV Friday video meeting until completion of our analysis this summer. First action towards developing new proposal : Brainstorming MiniWorkshop at KIAS March 11: 2 to 7h30 pm Regular (each 2 months) EVO meetings Workshop by end of 2011 in Paris GOAL: To have for FKPPL 2012, new proposal with hopefully already some results…!
