Developing common interest in Top/Higgs searches

• Both Korea and France have been working on top
  Physics
• gt top into dileptons (Korea)
• gt top into dilepton including one t lepton
  (France)
• gt 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 t
  leptons and as by-product
• the search for Higgs into t pairs and charged
  Higgs into t ?t
• This common research will bring an interesting
  breakthrough with
• the data recorded with the total Tevatron
  Luminosity (may be even a
• discovery if the t-channel is favoured ?) and it
  will be instrumental
• for the LHC.
• gtNeed of large amount of MC production (KISTI
  and CCIN2P3) and we also intend to include now
  data handling in both centers.

21
The TOP quark case
Interesting and not yet well studied case (in
progress) the top paire production with the
top decaying into t (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
22
t IDENTIFICATION only possible
in hadronic decay
BR50
t ? pp-p ?t (n p0)
BR14
Tagging and triggering based on
An inner cone, shrinking with energy, 1 or 3
good tracks
CDF detector and trigger system are especially
suited for the tau-related searches
23
Search for top into ts main motivations

• Goal 1 First time 3 s observation (not yet!)
• Goal 2 Check BR(t?t?b) wrt Standard Model
• BR(Wb) 100 ? Or Hb ??

• Training camp for BSM searches
• background of SUSY
• t dominant decay at large tan ß

25
Neutral SM Higgs into t-leptons
Important to look at different decay
mode (i.e. H?tt, not only H?
bb). Analysis optimized for SM Higgs,
but sensitive to
non SM Higgs. MSSM predicts a much
higher H-rate for large tanß in
gluon-gluon fusion, esp. in t-decay.
26
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
• B ? J/? F CP violation related studies
• CP even and odd measurement sin2ßs (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/? K0 competitive results with
  Babar/Belle (France)
• B ? J/? F, ?(2S) F (Korea)
• B ? J/? F, using new PID (dE/dx andTOF) and TTT
  (Two Track Trigger) gt sin2ßs (France)
• gt The Bs sector is crucial Physics for searches
  beyond standard model.

27
Bs key tool to explore matter-antimatter mystery
After measuring with an unprecedented precision
the oscillation frequency between Bs and
anti-Bs states,
we are measuring the lifetime difference
and the CPV phase in order to see
if any deviation with the SM
expectation.
Very high precision measurements gt a way
to look for New Physics. Important
breakthrough and even possible discovery with the
full Luminosity.

History 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)

Plan
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

• France-Korea CDF Physics Workshop
• Date June 2009 (exact date tbc)
• Place in Paris (?), Korea (?) or at FNAL (?)
• Agenda
• 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.
