CDF Experiment @ Fermilab Among the main assets of CDF:1st hadron collider experiment with a microvertex detector

1st & unique experiment with vertex tracking trigger capability (select b-quark at LV2)These two detector unique capabilities => 2008 Panofsky prize for Physics

Sophisticated & highly performing trigger:Level-1 tracking trigger and Updated LV1 trigger with FPGA clusters => very precise estimate of missing energy, τ ID, jet energy etc... Crucial improvements for BSM & Higgs

Improved recorded data quality and capabilityto cope with highest luminosity and even enhancing the Physics reach.BETTER DATA QUALITY AND MORE DATA First GRID running experiment

Accelerator & CDF performances

• Tevatron is the world highest energy accelerator at S=1.96 TeV until LHC takes over

• CDF will be able to take data until in 2010 and is discussing taking data in 2011

• Data processing and analysis will be done 4-5 more years after that.

• Data taken 5.8 fb-1 (January 31, 2009)

• Data taking CDF efficiency 80-85%

• 7 fb-1 till by 2009 04/21/23 9CDF-LIA, FKPPL in Lyon, 2009

Tevatron projection curves until end 2010

The running of the machine is still improving, it is believed Tevatron can deliver peak luminosity > 400 µb-1/s . Thus see next slide04/21/23 11CDF-LIA, FKPPL in Lyon, 2009

Why this LIA on CDF? Keeping CDF/Tevatron running beyond 2010

The Whitepaper, commissioned by the CDF spokespersons, scientific arguments for continued running with as benchmark: 2-3 more years with 2.5/fb/year delivered2012: 15/fb delivered and “10+” analyzable per experiment .

Developing common Developing common interest in Top/Higgs interest in Top/Higgs

searchessearches 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.


The TOP quark caseThe TOP quark case

Interesting and not yet well studied case

(in progress) the top paire production with the top

decaying into τ (see next)The Top quark and the Tau-lepton are crucial elements to look for New Physics But require highly performing and sophisticated detector and analysis

After measuring with an unprecedented precision the oscillation frequency between Bs and anti-Bs states,

Very high precision measurements => a way to look for New Physics. Important breakthrough and even possible discovery with the full Luminosity.

we are measuring the lifetime difference and the CPV phase in order to see if any deviation with the SM expectation.

History of CDF GridHistory of CDF Grid

LPNHE has been very active in the installation of DCAF and especially the development of GRID-CAF thanks to Subir Sarkar, post-doc 2005 and 2006 in collaboration with a few CDF-FNAL computing staff and CCIN2P3. (presentation of CDF-GRID pioneer experience at EPS-2006 by S. Sarkar)

Theory Bs Physics Top Physics and beyond (W’, Higgs related

searches) Brainstorming

Define the detailed agenda, organize/attend the workshop, set-up clear milestones and follow up.

Setting such a collaboration between teams that are quite far away took some time. It needed to clarify some misinterpretation within the Korean groups about the goals of this project; the aim is not only computing developments but also, and with a very high priority, developing an effective Physics collaboration, including PhD thesis co-advising. It took about six months to understand how and with whom to achieve this part of the project. We have converged now on how to proceed:
